Caldera 250/500 – Race Diary of the 2015 Grand Depart
“Confronted with the petty concerns of my ordinary life, I feel empty, as if I am wasting a priceless gift, the brief time that is allotted to each human for creativity… Can this longing and restlessness be the price that mortals pay for daring to trespass in the houses of the Gods? Mountains are not stadiums where I satisfy my ambitions to achieve. They are cathedrals, grand and pure, the houses of my religion. I approach them as any human goes to worship. On there alters I strive to perfect myself physically and spiritually. In their presence I attempt to understand my life, to exorcise vanity, greed, and fear. From the vantage of their lofty summits, I view my past, dream of my future, and with unusual acuteness I experience the present moment. I celebrate creation, for on each journey, I am reborn.” – Anatoli Boukreev / Above The Clouds

A motley bunch. The 2015 Caldera 250/500 starters (sans Keith – who hadn’t showed up yet, and sans George – off to the side talking to Matt Lee on the phone about his Spot issues).
Love that quote. Fitting as the Caldera 250/500 route has now been tested by the first batch of guinea pigs! We’ve been objectively claiming that this would be one of the toughest pound-for-pound routes around (if not the toughest) – and one of the most beautiful. Now that the dust has settled, and the lab rats have chimed in – we are definitely not liars. Below is a brief, informal race journal I kept as I spoke with riders and stalked blue dots (and one pink). If you’re lazy to read past this point, here’s the link to the Race Results and Arthur’s Strava File and the Rigs of the Caldera article in Bikepackers Magazine – those should give you some insight as well. Salute! –ps, sorry for not giving photo credits – thanks to all who contributed!
The START:
DAY 1 – 9/18/15
After a nice gathering at Gomez’s for some mexican food the night before, chilly 40 degree temps and uber clear skies greeted the riders at the 7am start in Mammoth. Some last minute Spot Tracker issues were handled, and we sent off the eager bunch at the official start time of 7:14am. The GD’s only singlespeeder, Keith Richards-Dinger, drove up, still in jeans, just as the group was about to depart. Being a veteran, he didn’t worry. He parked the car, changed, and it took him about an hour to get into the fold. The riders quickly sorted themselves out as Blake Bockius, Arthur Kopatsy, and Isaac Chilton found their way to the front of the charge. The first “course hiccup” was a mistake on my part that accidentally took a short jaunt on local photographer, John Dittli’s property. Luckily, he was there, and knew about the riders via Facebook, and helped everyone down the 0.5 mile route change that kept everything kosher and off a hillside that he’s been nurturing.
As night fell, the fastest riders made it into Big Pine before the gas station closed to resupply before climbing the Inyo Mountains. Blake and Arthur set a blistering pace for Day 1. Most others camped somewhere in the Coyote Flats, choosing to wait until sunrise and ambient light to handle the tricky, steep descent to Big Pine. Country Kitchen, and a nice big brekky was the ticket for many 🙂 The climb up Horton Creek to the day’s high point up Coyote tested riders’ grit and was a humbling reminder to all riders that this route is no joke.
DAY 2
Crazy happenings. Isaac Chilton forgot to turn his tracker on, but finally got it back on when he hit Bishop. Tony Symanovich had weird tracker issues as well, showing he was up near Reno. But he contacted us later in the day and confirmed he was still riding with Zak Tourville and was in good spirits.
First place rider pulls out:
Blake Bockius continued his fast pace with Arthur Kopatsy nipping at his heals. Everyone seemed to be settling into a nice groove, when reality struck. Even though he riding fast for “this route” – it was nowhere near as speedy as Blake was anticipating, and he realized he wouldn’t be able to finish the route in time to get back his work on time. From first place, he was officially the first rider to pull out from the race in Bishop at 1:11pm. He debated switching over to the 250 route, but did not have the track loaded. After struggling with the options for a bit, he decided to just pull out and come back and tackle the full 500 when he has more time.
Although unofficial, it appears (according to his blue dot) that George Reynolds left course before the Coyote climb on Day 1, and took the road into Bishop, bypassing a large section of the course.
The next to withdraw, was Kevin Hinton. He had an unfortunate mechanical while navigating some techy singletrack during the Inyo Traverse. He broke his derailleur in no mans land and was forced to abandon. Shortly thereafter, I got a call from Forest Baker, who was riding at a solid pace and had just arrived in Bishop. The hike a bikes had gotten to him, and he pulled out as well. Keith Richards-Dinger, the lone singlespeeder also notified me that he was abandoning the 500 and would continue on the 250. The Caldera route is breathing fire and showing it’s true colors. By the end of Day 2, Arthur was leading the charge, getting up towards the Glass Mountains, while Keith, Zak, Tony and Isaac were readying for the Volcanic Tablelands. Matt Reynolds made it to Bishop. Art de Goede, Danny Kaukola, Meade Plum, Jeremy Plum and Jeff Brooks stayed at various spots in the White Mountains for the night. 15 year-old Meade Plum continued plugging away with her dad Jeremy, making it to route mile 133 before bedding down for the night.
DAY 3
With renewed vigor, many were up and riding by 4-5am after just a few short hours of sleep. Arthur Kopatsy made his way into the Glass Mountains before the crack of dawn, while Keith, Zak, Tonny, Isaac, and Art de Goede grabbed some shuteye in various areas of the Volcanic Tablelands, or what Keith called the “sandpit from hell” when I cheered him on as he exited that section. Arthur continued past the turnoff for the 250 in the Glass Mountains and rode strong all the way to the steep climb into Bodie where he took a break and waited for the heat to subside before tackling it. He would up making it to Bridgeport just before sunset. What a blistering pace he’s been keeping!! As of Day 3, he’s the only 500 rider that’s passed the 250 turnoff.
Zak Tourville was riding strong but withdrew before the Glass Mountains climb, and rode Benton Crossing Rd and Highway 203 back to Mammoth – he needed to be ready for work the next day.
First 250 Finishers:
- Keith Richards-Dinger came in at 9:18pm on Sunday night 9/20/15 – giving him first place and the inaugural course record on the Caldera 250 with: 2 days, 14 hours, and 4 minutes – and he started the race late as he couldn’t get to the start line in time to begin with the rest of the riders. I was at the finish line waiting for him, and we took him to my house for a warm shower and bed. His only request, milk. He drank a lot of milk.
- Isaac Chilton and Tony Symanovich rode most of the last 25 miles with each other, and came through the finish line together at 11:26pm with official time of: 2 days, 16 hours, and 12 minutes. Unfortunately, both were having tracker issues, and I had no idea they were gonna finish that quickly – so I missed them at the finish line 😦
Jeremy and Meade Plum, Jeff Roberts, Matt Reynolds, and Danny Kaukola spent the night in Bishop, with hopes of getting an early start to the beat the heat. Danny broke his seat post clamp and has been trying to fix it with hose clamps, as the bike shop in Bishop is closed on Sunday. Arthur Kopatsy rode into Bridgeport to bed down for the night- smoking fast. Looking forward to tomorrow!!

Danny, still sporting a smile after losing his brand new Garmin and snapping the bolt on his seatpost clamp!!
DAY 4
Sadly, we got the announcement that Meade Plum and her dad, Jeremy are withdrawing. The hike-a-bike took a toll on her, and her achilles are very swolen. What a trooper. She made it to approximately route mile 161 and over 16,000′ of climbing. WOW!! Kudos to Meade!!!
Art de Goede was off to an early start, making his way up through the Glass, looking strong. Matt Reynolds and Jeff Roberts left Bishop nice and early to hit the Volcanic Tablelands. Danny Kaukola couldn’t get the hose clamps to work, so he’s off to the bike shop to get it repaired, and should be off and running soon. He’s also been having spot trouble, but is keeping in touch via texts.
Arthur Kopatsy left Bridgeport very early and is continuing to ride strong!! By 10:30am (as I write this), he reached the town of Belfort at 10,200′ on his way up to Mt. Patterson (the high point for the whole route). He’s currently at route mile 313 and still the only rider past the 250 turn off!!
10:30pm – update: Danny Kaukola officially scratched earlier today from Bishop, citing losing too much time trying to fix his broken seat post clamp. Only 4 remaining riders on course. Arthur Kopatsy has pushed past Walker and is now heading south with around 120 miles to go. Art de Goede is resting up in a motel in Bridgeport, getting ready for the Sweetwaters tomorrow! Jeff Brooks and Matt Reynolds are camping in the Glass Mountains around route mile 208. Might see some finishers tomorrow!
DAY 5 (7am)
still on course:
5pm update: Jeff Brooks and Matt Reynolds have finished the 250. They came in together at 4:13pm for an official time of 4 days, 8 hours, 59 minutes. Sweet!! There are no remaining 250 riders on course, and there are now officially 5 finishers of the 250.
That leaves one rider on course. Art de Goede. He crossed the Sonora Pass, and 250 finishers Matt and Jeff greeted him with cheers and encouragement at Leavitt Meadows campground, where they said he was in good spirits and just charging along. He made it to Obsidian Dome campground, where it appears he’s bedding down for the night before heading out to Molybdenite Creek tomorrow. Good luck, Art!! We’re all pulling for ya!!
He’s all done. Art de Goede crossed the finish line at 5:35pm. Only the 2nd person to complete the full 500. His official time is 7 days 10 hours 21 minutes. That makes 7 finishers out of 16 starters. That’s a wrap for the inaugural running of the Caldera 250/500 – hope to see y’all next year!!
Ride Report: Gull Lake Loop – June Lake, CA
If you are new to mountain biking, or want to take a short ride while spending the day in the beautiful town of June Lakes, this is a great ride for anyone. It’s mostly fantastic singletrack, offering up nice views of Gull Lake and the June Mountain Ski Area, and even slithers its way through a small aspen grove. This loop can be done in both directions, but the trailhead near Gull Lake Park is easier to find for your first time – so counter-clockwise is how we describe it here. It’s mostly flat, with just a couple short/steep efforts. If you’re looking for more riding nearby, check out the Yost Trail. While in town, don’t forget to grab a beer at June Lake Brewing and a kailua pig burrito from Ohanas – just a couple blocks from Gull Lake.
- Ride Type: Loop (counter-clockwise as we describe it, but it can be ridden both ways)
- Difficulty: Non-Technical, Easy with Minimal Climbing
- Time of Year: Summer and Fall (sometimes late Winter or Spring – depending on snow pack)
- Terrain/Conditions: Mostly smooth singletrack with a little doubletrack and a short stretch of pavement through the campground.
- Access: From Mammoth, take Highway 395 north for 20 miles to the southern turnoff for the June Lake Loop (Hwy 158). Drive for a little over 2 miles, through town. You’ll see signs for Gull Lake leading you down to the right. Once you reach Gull Lake Park on Granite Avenue, park by the tennis courts and the playground. The trailhead / ride start is directly across the street where you see the trail going steeply up the hillside.
- Length: 1.9 miles
- Approx. Time: 1/2 hour
- Lowest Elevation: 7,623′
- Highest Elevation: 7,711′
- Total Elevation Gain: 103′
- Bike Recommendation: This can be ridden with pretty much any off-road bike.
- GPX File: Available by contacting us
Turn by Turn (in miles):
0.0 – Start up the steep climb. Don’t be discouraged. It looks like a long hard climb, but after 20 yards you make a left turn and it flattens out.
0.5 – Continue straight, merging with the doubletrack trail, and heading up a short climb.
0.7 – Go left on the singletrack
1.0 – Reach an intersection with a fire road. Continue straight (you must curve to the right for 10 feet). After a short stretch, you’ll reach a blockade that only allows bikes and hikers. Descend here, and then go right at the T.
1.2 – Veer left at trail split, go over the bridge and pop out on pavement. Continue on the road to the left, taking you through the campground.
1.5 – The pavement turns to dirt and you pass a bunch of cabins. Continue straight on the dirt road.
1.7 – The wide dirt road narrows to singletrack.
1.8 – Go left, staying on singletrack. After a short, windy section, you emerge in the Gull Lake Marina parking lot. Continue riding straight out of the parking lot. It turns into Granite Ave.
1.9 – Turn left, staying on Granite Ave. The park is on your left, and the loop is complete. Do it again!!
Ride Report: Sagehen Summit Loop – near June Lake, CA
This loop is an oldie but goodie that we originally came across in the guidebook – “Mountain Biking the Eastern Sierra’s 100 Best Trails”. The tread is 4×4 doubletrack and dirt roads (with a short bit of pavement at the end) and tends to be soft and sandy in spots. Although it can be frustrating at times on a mountain bike, it is very enjoyable on a fat bike. It’s hard for me to imagine mountain bike pioneers doing rides like this in the early 90’s. But it’s definitely motivating, imagining them slogging through some of the beachy bits as my fattie floats over everything 🙂
From Highway 120, you climb steadily towards Sagehen Peak, and roll through a beautiful aspen grove (stunning when the fall colors are turning). There are marvelous views of Adobe Valley and the Glass Mountain Ridge and you can see all the way to the White Mountains as you start curving eastbound. When you turn north and descend into the valley, the views are again outstanding as you make your way across North Canyon Creek towards the last pavement climb back to your car. If you are seeking some stellar, buff singletrack, you will not get that on this ride. However, if you are in search of solitude and some of the amazing views that define Eastern Sierra adventure riding, this ride will please you and then some.
- Ride Type: Loop
- Difficulty: Non-technical, moderately strenuous climbing
- Time of Year: Spring, Summer, Fall (possible in late Winter/depending on snow pack)
- Terrain/Conditions: 4×4 roads and dirt roads (soft/sandy in sections) with the last 2.6 miles on pavement.
- Access: From Lee Vining, head 5 miles south on Highway 395 to the Junction with Hwy 120 towards Benton. Drive past the Mono Mills historic site and continue all the way to the top of Sagehen Summit (there is a sign). Park off on the dirt at the junction with froad 1N02. The ride starts here.
- Length: 17.2 miles
- Approx. Time: 2 – 3 hours
- Lowest Elevation: 7,283′
- Highest Elevation: 9,031′
- Total Elevation Gain: 1,896′
- Bike Recommendation: Fat Bike or Plus Bike (29er or 27.5 with 3″ tires). You can do it on a traditional mountain bike as well, but it’s not as enjoyable through the sandy sections, and you might be hiking your bike at times.
- GPX file: Available by contacting us
Turn by Turn (in miles):
0.0 – Start heading south on the wide dirt road 1N02 towards Sagehen Meadows. You’ll have a gradual climb with some steeper bits mixed in.

Ride Report: Tobacco Flats – near Mammoth Lakes, CA
In the mood to pedal hard and be rewarded with stellar views? If so, this ride is for you. If building lactic acid up in your legs isn’t in the cards, don’t bother. Tobacco Flats is a beautiful area accessed off of Mt. Morrison Rd. As you ride up the canyon, you’re confronted with Mt. Morrison straight ahead, McGee Mountain to your left (you can see portions of the road that switchbacks its way to the top) and Laurel Mountain to your right. We call this ride a “Tootsie Roll Loop” because you have out-and-backs at both ends, and a loop in the middle. Towards the end of the strenuous upper out-and-back portion of the ride, you are rewarded with a rare perspective of Convict Lake at an overlook point. Take a moment to soak it in. Then it’s just a short burst to the top of the climb before turning around beginning the invigorating descent. Before you know it, you’ve dropped 1,600′ and are back at your car. Fantastic!
- Ride Type: Tootsie Roll Loop (Loop with out and back at each end)
- Aerobic Difficulty: Steep climbing is strenuous, strong legs and lungs a must
- Technical Difficulty: Non- technical
- Time of Year: Summer and Fall (sometimes late spring – depending on snow pack)
- Terrain/Conditions: Mostly doubletrack – gorgeous scenery.
- Access: From the junction of Highway 395 and the 203 at Mammoth Lakes, drive south on the 395 for 5.2 miles and exit at Mt. Morrison Rd. Drive 0.2 miles and turn left at the cemetery. Drive another 0.1 miles and park near the Snowmobile Information Kiosk next to the green building. The ride starts here.
- Length: 8.5 miles
- Approx. Time: 1.5 – 2.5 hours
- Lowest Elevation: 7,026′
- Highest Elevation: 8,417′
- Total Elevation Gain: 1,647′
- Bike Recommendation: This can be ridden with pretty much any off-road bike, although fat bikes and plus bikes seem to enjoy the potentially soft conditions the best.
- GPX File: Available by contacting us
Turn by Turn (in miles):
0.8 – At the junction, continue straight/right and start climbing towards the west.
2.4 – Continue straight.
2.6 – Continue straight. Shortly after, reach a 4-way intersection. Go right, continue climbing
2.8 – Veer right at the Y. Continue climbing.
3.3 – It flattens for a brief moment. Enjoy the break, continue straight, and climb some more.
3.8 – You reach a flat open area. The best viewpoint for the Convict Lake is here.
4.0 – Reach the end of the trail. Time to start the descent, back the way you came.
4.2 – Pass the Convict Lake Lookout again – make sure to take a photo if you haven’t already!
5.4 – You reach the 4-way intersection where you started the “out-and-back” at mile 2.6. Continue straight to finish off the loop. Buckle up for a fast and beautiful descent!! Stay on this road as it loops around to the north right above Highway 395.
7.7 – You reach the junction from mile 0.8. You’ve finished the loop, now turn right to start backtracking to your car. One short, steep climb and then the final descent to the finish.
8.5 – Ride ends at the Snowmobile Information Kiosk. Pat yourself on the back. Great ride!
Keeping it Fat in the Tetons and Grand Targhee
Alan's Mountain Biking Adventures
The opportunity to ride fat bikes in Grand Teton National Park doesn’t present itself that often, so I jumped at this chance. Teton Mountain Bike Tours led a group ride in the National Park as part of the Fat Bike Summit. Local advocates are vying for more winter riding opportunities alongside snowmobiles in GTNP and in Yellowstone. But for now, fat bikes are limited to plowed roads that cars can drive on. So as far as riding goes right now, the terrain is nothing amazing – but you’re still in the Tetons, enveloped by some of the best eye candy that Mother Nature has ever created.
Riding on one of the plowed roads in Grand Teton National Park. Notice the socked in cloud layer.
Unfortunately, during our ride, we we socked in with cloud cover, and the Tetons never poked out. About an hour after our ride…

Ride Report: Moraines and Meadows Loop – Lee Vining, CA
This is one of the earliest “signed” USFS bike routes in the region. These days, it’s rarely ridden and not many people even know it exists. Did you know about this ride? It’s mainly double-track and 4×4 roads, but this is still one heck of a rewarding ride! Right off the bat, you get a great perspective of Mono Lake and Paoha Island as you wrap around to the south and get your legs warmed up. Before long, you turn east, and start climbing toward Lower and Upper Horse Meadows. Although this is a long, strenuous climb (as the elevation profile below will attest to), you get majestic views of the Dana Plateau and Mt. Gibbs to help you forget about your lungs and legs yelling at you. Eventually, this climb ends and you turn to the south. Now you’re stung with views of June Mountain as you start to drop. Your climbing efforts are mostly done by this point. As you wrap around Williams Butte, views of the Mono Basin hug you as you return every foot of elevation you took earlier. You’ve gotta ride through a junkyard of sorts, before making the short climb back towards you car, and you’re done. Good work! Also close by are the Bennettville Ride, Saddlebag Lake Trail and the Log Cabin Mine Loop if you’re up for more riding.
- Ride Type: Lollipop (loop with short out and back)
- Difficulty: Non-technical, moderately strenuous with one sustained climbing effort
- Time of Year: Summer and Fall (sometimes late spring – depending on snow pack)
- Terrain/Conditions: Doubletrack, 4×4 roads
- Access: From the junction of Highway 203 and 395 at Mammoth Lakes, drive north on the 395 for 25 miles. Exit and go left on Highway 120/ Tioga Pass. Drive 0.9 miles and look for an interpretive kiosk with a dirt parking area to your left. If you look closely, you’ll also see an old Forest Service sign for the “Moraines and Meadows” ride. Park here. *Note: Mobil Mart (open seasonally) is a great spot for post-ride grub, and you pass right by it at the junction of the 395/120.
- Length: 11.9 miles
- Approx. Time: 1.5 – 2.5 hours
- Lowest Elevation: 6,769′
- Highest Elevation: 7,898′

Road Trip – Global Fat Bike Summit 2015: Jackson, WY
Alan's Mountain Biking Adventures
For the 2nd year in a row, I jammed out to the Fat Bike Summit with a crew from Mammoth. Last year, it was in Ogden, UT – read about it here. This year, it was at Snow King Resort in Jackson, WY. For those that don’t know, Snow King is the O.G. ski resort right in the heart of Jackson that opened in 1930. Gets overshadowed by Jackson Hole Resort 12 miles up the road – think of it like June Mountain compared to Mammoth Mountain, except you can night ski for $25!
Rolling from the Antler Inn to Snow King – let the Summit begin!
Anyhoo, jumped in the turbo diesel Jetta Wagon with Jen and Dan at 5:30am. Bikes and skis and fritos and tangerines packed. Wyoming bound. After driving about 4 hours each, and Dan only stalling 3 times, we hit the town square. Checked in…

Ride Report: Casa Diablo Overlook – Mammoth Lakes, CA
This is a fairly strenuous 10-mile loop that is just across the highway from Mammoth Lakes. It starts with a nice climb behind the geothermal plant, giving you an interesting perspective of the area. Long before the geothermal plant was built, this area was called Casa Diablo. At one time, there were hot springs and an active geyser here. It was a stagecoach stop around 1880, and tourist attraction in the 1920’s. Even earlier than that, Native Americans had an obsidian mine here. As you’re riding, look around at all the whitish areas on the slopes, created from geothermal activity of the Long Valley Caldera.
Eventually you reach Antelope Springs Road and continue climbing this graded road before making a a right for a gorgeous descent down into the valley below. The views of Mt. Morrison and the Sierra Crest are magnificent. Before long, you turn right again, and start the climb to the Casa Diablo Overlook. As you get near the top, you’ll be riding over lots of beautiful obsidian. From the top, you can look west to Mammoth Mountain and see the geothermal plant below. You can look to the south to see Crowley Lake and Doe Ridge, while to the east Hot Creek and the Long Valley Caldera are visible. It’s a magnificent viewpoint and well worth the effort. Afterwards, you complete the loop with fun descent including some rarely ridden singletrack (super fun, with a couple bits of hike-a-bike).
A very similar route, that is longer and has some more climbing, is the Little Antelope Valley Loop. Big Smokey Loop and Little Smokey Loop are also related to this ride, and can be combined for an epic day in the saddle. Confused? Contact us and we’ll dial in a ride to suit you.
Overall, the terrain can tend to be on the sandy side in sections (especially in the summer), so this is a great ride for fat bikes or 29+ bikes. You can do it on a regular mountain bike, but be prepared for some sandy hike-a-bike sections.
- Ride Type: Loop
- Difficulty: Non-Technical, moderate to strenuous climbing with a couple short, steep spots
- Time of Year: Spring, Summer, Fall (possible in Winter/depending on snow pack)
- Terrain/Conditions: Mostly smooth double-track and fire road with some soft & sandy sections.
- Access: From the junction of Highway 203 and Highway 395, go east on the 203 (away from Mammoth) towards the geothermal plant. Make a right turn on Old Highway 395. After approximately 0.2 miles look for a dirt parking lot on your left. Park here, this is where the ride starts.
- Length: 10.0 miles
- Approx. Time: 1.5 – 2.5 hours
- Lowest Elevation: 7,106′
- Highest Elevation: 7,924′
- Total Elevation Gain: 1,449′
- Bike Recommendation: Fat Bike or 29+ because of the sandy sections, but any mountain bike will suffice.

Ride Report: Little Antelope Valley Loop – Mammoth Lakes, CA
This is a strenuous loop that is just across the highway from Mammoth Lakes. If you are looking for something different, want to give your lungs some work, and enjoy serenity with outstanding views – give this ride a shot. If this ride is intriguing to you, but you want something a little shorter – try the Casa Diablo Overlook Ride – it’s very similar. You can also tack on a little more climbing to this ride by including the short (but steep) out and back to the Casa Diablo Overlook. If you want an epic day in the saddle, Big Smokey Loop and Little Smokey Loop connect with this route as well. Confused? Contact us and we’ll dial in a ride to suit you.
The Little Antelope Valley loop has three main climbs, and each is rewarded with spectacular views and smiley descents. You start with a mild climb to get your blood pumping as you make your way around the backside of the the local geothermal plant. As described in the Casa Diablo Overlook Ride, this is where Casa Diablo once existed. From there, you continue climbing towards Little Antelope Valley before a speedy descent towards the valley floor. You’re greeted with views to the Chalk Bluffs and Long Valley Caldera as you descend. You then head south and climb some more, before the views open up again and you descend on the west side of the Hot Creek Gorge (should be short for “gorge”ous). After making your way past an active geothermal pool (“The Jacuzzi) one last climb awaits. The ride finishes with a short but sweet section of rarely ridden singletrack. This last piece of ST is mostly rideable, but you’ll probably have to dismount once or twice – during a tight switchback and some techy bits. Next thing you know, you’re back at the car wishing you took more photos.
Overall, the terrain can tend to be on the sandy side in sections (especially in the summer), so this is a great ride for fat bikes or 29+ bikes. You can do it on a regular mountain bike, but be prepared for some sandy hike-a-bike sections.
- Ride Type: Loop
- Difficulty: Non-Technical, Moderate to Strenuous Climbing
- Time of Year: Spring, Summer, Fall (possible in Winter/depending on snow pack)
- Terrain/Conditions: Mostly smooth double-track and fire road with some soft & sandy sections.
- Access: From the junction of Highway 203 and Highway 395, go east on the 203 (away from Mammoth) towards the geothermal plant. Make a right turn on Old Highway 395. After approximately 0.2 miles look for a dirt parking lot on your left. Park here, this is where the ride starts.

Ride Report: Wagon Wheel Trail – Near Mammoth Lakes, CA
Wagon Wheel Trail is a fun little piece of trail that descends rapidly from Swall Meadows Rd. until it connects with Lower Rock Creek Rd. As the name suggests, it used to be an old wagon trail that has deteriorated over the years. It can get loose and sandy in sections. There are also extended sections of slickrock and various rock gardens that make this very fun on a full suspension rig. Not many people climb it, but if you’re a climber who likes some technical challenge with a bunch of fun slickrock step-ups, give it a shot both ways. Most people connect it with the Sand Canyon Trail to add a little more descending and mileage. Since it’s only 2 miles, and it’s over pretty quickly, it’s not usually ridden on its own. It’s often gets overlooked by the nearby Lower Rock Creek Trail, but if you’re shuttling LRC, it’s worth it to hit Wagon Wheel either before or after, since you drive right by it.
- Ride Type: Point to Point – as described here
- Difficulty: Intermediate/advanced descending skills required. Some technical rock gardens and sandy sections.

0.0 – No directions for this one. Simply stay on the trail until it ends by merging with Lower Rock Creek Rd. after 2 miles. If your shuttle ride is waiting for you, jump in. Otherwise, ride back up the road, or if your lungs and legs are up for it, ride back up the trail.
Ride Report: Winter Snow Riding in Rock Creek Canyon
Come Winter time, Rock Creek Rd. is plowed so you can drive up 6 miles past Tom’s Place to the East Fork / Sno-Park area. This plowing is paid for by the fees collected at the Sno-Park. It costs $5/day to park or you can get a season pass for $25. It’s well worth it. Don’t even consider poaching unless you want bad karma and a $94.50 ticket. Beyond the Sno-Park, Rock Creek Rd. is gated shut and it’s open to nordic skiers, snowshoers, and other non-motorized Winter users looking to access backcountry skiing, etc. Rock Creek Lodge remains open with limited hours during the Winter, and often shuttles people to/from the lodge via snowmobile. Note: Snowmobiling is NOT allowed other than in conjunction with the lodge’s operations. Once there’s enough snow, they also groom the road and a small network of nordic trails with fresh corduroy under permit from the Forest Service. They offer great dinners and xc skiing – you should check it out.
So how does all this relate to fat bikes?? In two ways:
First, there is a summer trail that travels along the creek, all the way to Rock Creek Lake. In the Winter, it gets packed by snowshoers and hikers. When conditions are right, it’s one of the best snow singletrack trails you’ll encounter in the whole region. Lots of small bridges, some technical sections, but mostly smooth, flowing goodness with a remote feeling you don’t get here in the busy season (the campgrounds that the trail passes through are bustling all Summer long). Because it’s never groomed, it remains legal to fat bikes all Winter.
Second, there’s a window every Winter (in recent years, a fairly large window) where Rock Creek Rd has enough snow to ski, snowshoe, fat bike, etc – but not enough to groom. During this time frame, when the road is packed via human and snowmobile power, it is legal to fat bike. Just like everywhere else in the Inyo NF, once grooming has commenced for the season, fat biking is explicitly prohibited.
In some parts of the Inyo, there are online grooming reports, like this one – which helps keep track of legal fat biking opportunities. There is no online grooming report for Rock Creek Rd. We recommend riding the snow singletrack, but if you intend to ride on the road, please call Rock Creek Lodge to confirm whether or not grooming has begun for the season. . They are super friendly and well-versed in fat biking. They’ll let you know the grooming status and if conditions are welcoming to fat bikes. There might be times when it is “legal” to ride, but they’d prefer we don’t based on conditions – PLEASE RESPECT their requests. We want to foster a good relationship with the lodge and all user groups – so please ride RESPONSIBLY and LEGALLY.
In addition, if you do ride the road, make sure to extend courtesy to all other user groups, stay to the right, and in snowmobile tracks when possible. Stay in control, and use proper etiquette when passing other users on the descent. Basically, use common sense!!
Ok. So now that all that jazz has been discussed, get up there. It is stellar. Definitely worth the half hour drive from Mammoth and $5.
- Ride Type: Out and Back
- Difficulty: Mostly non-technical (some rock gardens and many bridges keep you on your toes), moderate to heavy exertion based on conditions
- Time of Year: Anytime after it’s snowed and been human-packed for the singletrack portions, and before snow grooming has begun on the Rock Creek Rd. portions
- Terrain/Conditions: Singletrack / Wide road
- Access: From Mammoth, take Highway 395 south approximately 19 miles, and exit at Tom’s Place. Drive up Rock Creek road approximately 6 miles to the Sno-Park at the winter road closure. Park here, put $5 in the envelope at the kiosk, and put the stub on your dashboard.
- Length: 9.8 miles
- Approx. Time: 1.5 – 2.5 hours

Fattie Style Singletrack Snow Riding on Uptown Downtown Loop
Alan's Mountain Biking Adventures
Yesterday was blast and day of firsts for many Fat Bike Mammoth peeps. Last year, a couple of us started snowshoe “fatpacking” the 4.25 mile Uptown/Downtown loop (up to the Earthquake Fault and back). Then we’d reap the reward of our efforts by riding bikes on the glorious snow singletrack. This year, we’re doing the same thing except for one extra ingredient – a local friend and Fat Bike Mammoth’er is now renting bikes 🙂
Getting ready to roll out in the Community Center Parking Lot
*PLUG – if you wanna ride a fat bike, give Jen a call/text – she’s got the goods – 760-914-0675
Sooo… instead of just two or three of us getting the stoke of riding the shreddiest snow singletrack around, we were able to share it with 12 people yesterday!! That may not seem like a lot, but for a small mountain biking/fat biking club…

Ride Report: Laurel Settling Ponds Loop – Mammoth Lakes, CA
Cruising around the Laurel Settling Ponds is a peaceful ride to do pretty much year round. It’s nice in the Summer on dirt, and it’s usually rideable in the Winter on snow with a fat bike (trucks and snowmobiles tend to pack this area out nicely). The views are spectacular in every direction – Mammoth, The Sherwins, Crowley Lake, The Glass Mountains, etc. and the settling ponds themselves are very scenic. It’s pretty mellow cruising, with hardly any elevation gain. Great to take the dog on a leisurely outing. If you’re looking for more, you can link this the Sherwin Creek/Mammoth Creek Rd. ride. There’s also ample opportunity to explore the many forest service roads in this area, and you can head all the way to Convict Lake. Contact us with any questions about putting a great ride together.
- Ride Type: Lollipop (as described here – many variations exist)
- Difficulty: Non-technical, mild exertion
- Time of Year: All year (as long as trucks and OSV’s have packed the snow in the winter, you can ride with a Fat Bike)
- Terrain/Conditions: 4×4 roads and doubletrack
- Access: From the town of Mammoth Lakes, drive down Highway 203 towards Highway 395. Just before getting on the 395 south, there’s a turnoff on Mammoth Creek Rd. There’s a small parking area here, and oftentimes a Winter closure gate once the snow flies. Park here and start riding south.
- Length: 9.1 miles
- Approx. Time: 1-2 hours
- Lowest Elevation: 7,115′
- Highest Elevation: 7,258′
- Total Elevation Gain: 305′
- Bike Recommendation: XC Mountain Bike during Summer/Fall or Fat Bike at low psi during Winter / snow
- GPX File: Available by contacting us
Turn By Turn Directions (coming soon): – For now, just go out and explore. It’s hard to get lost, as you can always see landmarks and you’re never far from Sherwin Creek Road or Highway 395.
Ride Report: Sand Canyon Loop near Mammoth Lakes, CA
This is one tough ride. It takes the Sand Canyon Mountain Bike Trail, which is usually an epic shuttle ride, and massages it into one badass mamma jamma loop. Start at Tom’s Place Resort and make the climb up Rock Creek Rd to access Sand Canyon. After descending Sand Canyon you take Forest Road 4S54 to the left to complete the loop back to your car. You’ll be ready for some post-ride beer and grub at the restaurant. They also have great milkshakes. Another great spot for some mid-ride yummies is Pie In The Sky at the Rock Creek Lake Resort. Grab a slice before turning left at Rock Creek Lake and starting your final push up to the Sand Canyon MTB Trail. From the top, it’s pretty much a bomber 4,000′ descent with great views in every direction before some tough and sometimes sandy climbing back to your car. If you’re in the mood to explore and climb even more, you can take the Wheeler Crest Out and Back about 4 miles after you hit the dirt. You can also include the Swall Canyon Trail, Wagon Wheel Trail, and Lower Rock Creek Trail for a custom loop of epic proportions.
If you have questions about any of this or tailoring a ride to suit you, send us a note.
Note: Much of this ride is very remote. Please be self-sufficient and carry plenty of water and nutrition as well as items to fix your bike in a jam. Weather frequently changes as well, so be ready for anything!!

Ride Report: The Double High Five Y
Everybody’s first response to this one is, “Huh?”
This is a great ride for climbers and endurance nuts that want to earn some great turns. You’ve gotta be game for some lung punishment.
Its a fairly easy route to navigate, since it’s a combo platter of three classic out-and-back rides: Mountain View Trail, Starkweather Trail, and Hard Core Trail. Starkweather and Hard Core are 5 miles each and Mountain View makes the stem of the “Y” (see the map below) – Hence the weird name. With 3,600′ of climbing over 22 miles, it doesn’t matter what you call it – it’s a mini epic that’s worth every penny of sweat equity. ** Note: Starkweather Trail is seasonal – so make sure it’s legal before hand.
- Ride Type: Three Out and Back’s
- Difficulty: Intermediate to advanced climbing and descending skills required. This is some lung-buster climbing with high speed descents.
- Time of Year: Late Spring and Fall (dependent on when Starkweather is open)
- Terrain/Conditions: Singletrack, Double Track
- Access: From town, drive up Highway 203 towards Main Lodge of Mammoth Mountain Ski Area. Make a right turn at the “Earthquake Fault” sign. Park in the lot. There is a trailhead near the bathrooms for Mountain View Trail. Start heading up and turn right at the T to start the ride.
- Length: 22.3 miles
- Approx. Time: 3-4 hours
- Lowest Elevation: 7,991′
- Highest Elevation: 10,244′
- Total Elevation Gain: 3,599′
- Bike Recommendation: Lightweight XC mountain bike is best. Full suspension or hardtail.

Ride Report: Inyo Craters Singletrack – Mammoth Lakes, CA
Inyo Craters Singletrack is a sweet little section of trail that doesn’t get ridden as much as it should. After a great flowy section, you reach a parking area where it connects with an old jeep road that takes you up to the Inyo Craters Lookout. Here you must park your bike, as it’s illegal to ride bikes on the trails around the craters. There are some picnic tables, interpretive signs, and it’s a nice place to hike around and eat a snack before heading back down. This ride is short on it’s own, but splendid when combined with the Inyo Craters Loop or Inyo Craters Fat Double Lollipoop.
*Note: There are some hiking only trails up to the Inyo Craters – please do not ride your bike on those. Stay on the route listed here.

Ride Report: Inyo Craters Loop – Mammoth Lakes, CA
The Inyo Craters Loop is an old school Mammoth ride. It was one of the earliest USFS signed bike routes. Other than the Inyo Craters Singletrack (which we include with our version of the loop), the terrain is pretty much jeep roads. There is moderate climbing, with some sweet views and a good tour of the area. This is a relaxing ride that’s definitely worth doing for some peaceful exercise. If you want a little more ride time / exertion, try the Inyo Craters Fat Double Lollipoop.
This ride goes around the two Inyo Craters, which were formed from a volcanic explosion 1,500 years ago. Pretty cool.
Soon after finishing the singletrack section, you ride out of the forest and a huge pumice flat opens up in front of you. 360 degree wicked views await, including San Joaquin Ridge and White Wing Mountain. Next you enter a Jeffrey Pine Forest and cross Deadman Creek before paralleling the creek and curving around and starting back towards the craters. After a peaceful ride through the forest, you arrive at the main parking lot. Lucky for you, you get to ride the singletrack back the way you came. Nice!
**NOTE FOR WINTER / FAT BIKE RIDING – This route is usually packed by snowmobiles and trucks before grooming starts for the season. Other than the singletrack section (which sees no Winter use) the rest is usually fun on a fat bike with low tire pressure. Remember, once grooming starts, all groomed trails are OFF LIMITS to bikes. Click here for the grooming report to see if it’s currently legal to ride. Questions? Contact us.

Ride Report: Bennettville Trail near Yosemite, CA
The Bennettville ride is a must do if you’re in the area. It’s right by the gate to Yosemite, and takes you back to a time in the 1880’s when this area was being mined for silver. The trail is an old mining road (much of it is actually on the old Great Sierra Wagon Road) that has narrowed into great singletrack in many parts. It takes you to the ghost town of Bennettville, where two buildings are still standing – an office and a large barn. On the way there, you pass by small reflecting lakes and the Great Sierra Tunnel. This mining tunnel goes over 1,700′ into the earth. A pretty amazing feat.
Now, the tunnel is gated off and there’s a small water stream trickling out. There is still old mining equipment laying around as well, and you can see the old rail tracks going into the mine.
This ride is pretty short, so you might want to combine it with one or more of these other rides in the area: Saddlebag Lake Trail, Log Cabin Mine Loop, or Moraines and Meadows Ride.
- Ride Type: Out and Back
- Difficulty: Non-technical, pretty easy
- Time of Year: Summer and Fall (sometimes late spring – depending on snow pack)
- Terrain/Conditions: Historic Wagon Road with many singletrack sections
- Access: From the junction of Highway 203 and 395 at Mammoth Lakes, drive north on the 395 for 25 miles. Exit and go left on Highway 120/ Tioga Pass. Drive up Tioga Pass for 10.95 miles and look for an unmarked turn-off to the right (opposite Tioga Lake). It’s a little hard to find, as it’s no longer labeled or signed (some of the older guidebooks state there’s a Bennettville sign, but as of 2014, it’s no longer there). If you’ve reached the Tioga Lake Overlook, you’ve just past it. Head back down with your eyes peeled to the left, and you’ll see the turnout easier heading down the mountain. You can also park at the Tioga Lake Overlook and just ride your bike down to the ride start. The ride begins where the boulders are blocking the old mining road.
- Length: 2.92 miles
- Approx. Time: 30 – 45 minutes (or more if you spend time hiking around the area)
- Lowest Elevation: 9,734′
- Highest Elevation: 9,873′
- Total Elevation Gain: 307′
- Bike Recommendation: This can be ridden with pretty much any off-road bike.
- GPX File: Available by contacting us
Turn by Turn (in miles):
0.0 – ride starts at the boulders blocking the road
0.12 – veer left then soon start climbing. views of Tioga Lake to the right

2.92 – ride ends at the boulders, where it began
Ride Report: Saddlebag Lake Trail near Yosemite, CA
This oft forgotten singletrack trail is not ridden enough. Most people are unaware that it even exists, much less that it’s open to mountain biking. It is tucked cleverly between Yosemite National Park and the Hoover Wilderness, butting right next to the Wilderness Boundary in a couple of spots. It’s only a 45 minute drive from Mammoth. Although the ride is short (only 4 miles), it’s definitely not short on exquisite views!! There’s minimal climbing, but there are some technical sections that will surprise you, and some punchy efforts that will get your heart rate up. Much of the trail is fairly smooth, but there’s also a fair share of rocks and shale that sneak up on you. Be ready for it. We describe this ride as a loop. Most people do it as a loop. However, the last section of trail (approx. 1.5 miles) is almost all rock and shale, and not much fun for less skilled riders. If you’re doing the full loop, full suspension or a fat bike will help. Most people will have to hike some of the obnoxious sections. In our opinion, the best part of this ride is the first half. The best terrain, trail quality, and views are had while riding the the east and north side of the lake, right up until you reach the Forest Service cabin. Therefore, we’ve written directions for the full loop, but also notated the out and back to the cabin. Your choice, just wanted to give fair warning.
Also in the area are the Bennettville Ride, Log Cabin Mine Loop, and Moraines and Meadows Ride. You might want do one or more of those rides to make a great day of riding. Saddlebag Lake is also a great spot to fish, or just hang out with the family and make a day out of it.
- Ride Type: Loop (counter-clockwise is the way we recommend), or out and back to the cabin
- Difficulty: Moderately technical (some rocks and shale), but pretty easy on the lungs
- Time of Year: Summer and Fall (sometimes late spring – depending on snow pack)
- Terrain/Conditions: Almost all singletrack, some smooth, some shale/rock gardens – with gorgeous high alpine scenery and lake views everywhere
- Access: From the junction of Highway 203 and 395 at Mammoth Lakes, drive north on the 395 for 25 miles. Exit and go left on Highway 120/ Tioga Pass. You’ll pass the Mobil Mart on your left. You might want to stop here later for some great grub and live music depending on time of year you are riding. Anyhoo, continue driving for 10 miles and turn right at the Saddlebag Lake Sign. Then drive for another 2.5 miles on a mostly dirt road. Go to the parking lot at the end of the road and spot the restrooms to the right. The trail sign is just past the restrooms.
- Length: 4.1 miles
- Approx. Time: 45 minutes to 1.5 hours for the loop (shorter for the out and back)
- Lowest Elevation: 10,055′
- Highest Elevation: 10,192′
- Total Elevation Gain: 361′
- Bike Recommendation: This can be ridden with pretty much any off-road bike, but full suspension or fat bike is recommended for the western portion of the loop.

- Other Reference: Hunter’s Saddlebag Lake Trail Blog
Turn by Turn (in miles):
0.0 – Start at the trail sign, heading around the lake to the right (counter-clockwise). Right off the bat, there are a few sections of rock and shale that will warm you up quickly.
.50 – The trail opens up to smooth flowing singletrack with some great lake views
.75 – Cross a small creek
.85 – Rocky climb. Once you crest the climb, views of the rest of the lake become apparent. The trail now strays from the shoreline a bit and meanders through pine trees and stays a little cooler.
2.07 – Arrive at the old cabin on the left
** If you choose to do this ride as an out and back, this is the turn around point. Simply retrace your steps and go back the way you came. If you’re continuing to complete the loop, keep following the cues below:
2.1 – You reach a Wilderness trail sign to the right. Do not take this. Continue straight across the creek bed.
2.25 – You reach another Wilderness trail sign letting you know that you’re about to enter Wilderness. Do not take it. Instead a few yards before the sign, there is a singletrack trail to your left. Take this to continue the loop you are on.
2.35 – There is a small bridge with a couple of logs to your left. It’s hard to see as it’s surrounded by brush. Use this bridge to cross the creek. Don’t miss this turn!! Just after the creek crossing, there are a couple of techy rock gardens and one short climb to navigate.
2.52 – Go left at the junction with another trail. You’ll now enter the most hateful portion of the ride. Rocks and shale make for annoying riding all the ay home.
3.69 – Reach the bridge. Cross the bridge and take the singletrack to your left which will bring you back to the parking lot.
4.1 – Arrive at trail sign and finish ride.

The first trail sign you come across marking the route to Lundy Lake. Do not take this! No bikes allowed.

Parked on the bridge. I forgot to cut my number plate off after the VC race earlier in the week. Oops.
Ride Report: Obsidian Dome Loop near June Lake, CA
This ride can be a sandy mess. There are a couple of sections that actually look more like sand dunes than a bike trail. With that caveat, it’s still worthwhile… even without a fat bike. Of course, it’s most enjoyable on a fat bike 🙂 There is no singletrack – it’s pretty much all jeep roads and wide graded dirt roads. Ok, so what’s the upside? You do get some nice views and a chance to get up close and personal with Obsidian Dome as you ride all the way around it. Black, volcanic glass is abound on the 300′ high, mile-wide “dome”. It’s worth laying your bike down and hiking to the top of the dome. I wouldn’t necessarily travel to this are just for this ride. There are many other trails within a 5-10 10 minute drive. For example: Yost Meadows Trail, Hartley Springs Loop, and Bald Mountain Ride are all close by. If you are making the journey out to the area, you might wanna give one or more of those a try as well.
- Ride Type: Loop
- Difficulty: Easy technically, with a couple tough climbs in sandy terrain (dependant on OHV use)
- Time of Year: Summer and Fall (possibly late spring depending on snowfall)
- Terrain/Conditions: Mostly doubletrack/ jeep roads with some very sandy sections
- Access: From Mammoth, go north on Highway 395 for 11 miles. Turn left on Obsidian Dome Rd (across from Bald Mountain Rd). Park in the dirt area near the kiosk.
- Length: 7.2 miles
- Approx. Time: 1-2 hours
- Lowest Elevation: 7,856′
- Highest Elevation: 8,352′
- Total Elevation Gain: 776′
- Bike Recommendation: Fat Bike is best and makes the sandy terrain fun, but any mountain bike will do.

Sandy crap fat bike style
2.0 – Reach a USFS kiosk with a map. Go straight on 2s11 and start climbing.
2.5 – Veer right at the intersection. You’ll start to get some nice views here as you ride towards Obsidian Dome.
4.2 – Hardest sandy climb of the ride
4.7 – Turns into 2s79. Climb for a bit, then pass the Obsidian Dome Parking Area and the road widens and becomes well graded. Descend back to your car.
7.2 – End of ride.
Ride Report: Yost Meadows Trail – June Lake, CA
Yost Meadows Trail is one of the most under-rated and overlooked trails around. It’s super easy to access, with parking right off the June Lake Loop. The first mile or so is brutal climbing, with no warmup, that usually involves serious granny-gear pounding or hike-a-bike if you’re on a singlespeed (like me). But the views you get of June Lake and Gull Lake make you forget that you’re wheezing and gasping for dear life. Take a moment to soak it in. The climbing mellows a bit after this point as you spin through alpine meadows and aspen groves. By this point, you’re probably imagining how much bliss this singletrack will be on the way back down! Eventually you enter the ski area- and the trail descends a little before crossing under the lift and climbing some more. The trail is usually pretty easy to follow, but it might be good to load the gpx file (contact us to request the file) especially if any snow has fallen. Also, you must be aware that you have to stop at 3.6 miles and turn around. There is a boundary here for the Owens Headwaters Wilderness Area and bikes are strictly prohibited past this point. Last time we rode it, there was no visible “Wilderness Boundary Sign” so it’s on you to be responsible. You MUST NOT RIDE YOUR BIKE IN THE WILDERNESS AREA. We recommend using an app on your phone or carry a GPS device so that you can track your mileage. Feel free to park the bike and continue hiking past this point. By foot, you can get to Yost Lake and Fern Lake – both great spots to eat some grub and relax. Anyhoo, once you turn around, it’s pretty much rip-roaring downhill fun all the way back to the car. There are hikers once in a while, so be wary – and remember to stay in control in the exposed areas and steep switchbacks. Now go ride!
Note: The best part of the trail (arguably) is the 2.2 miles from the parking area to the ski area – so that’s a good turnaround point as well, if you want to cut the ride a little short or don’t want to mess with getting near the Wilderness Boundary
- Ride Type: Out and Back
- Difficulty: Advanced climbing and descending skills required. This is a lung-buster climb with exposed descents.
- Time of Year: Summer and Fall (possibly early Winter/ late Spring depending on snowfall)
- Terrain/Conditions: Singletrack, with some loose/sandy sections
- Access: From Mammoth, take Highway 395 north for 20 miles to the southern turnoff for the June Lake Loop (Hwy 158). Drive for about 2 miles. You’ll reach the Fire Station and the Balancing Boulder on the right side of the road. The dirt parking lot is on the left, directly across from the fire station. You’ll see the trail sign.
- Length: 7.2 miles total (3.6 to the Owens Headwaters Wilderness Boundary)
- Approx. Time: 1.5 – 3 hours, depending on skills and comfort level
- Lowest Elevation: 7,718′
- Highest Elevation: 9,250′
- Total Elevation Gain: 1,678′ (with around 1,500′ coming in the first 3.6 miles – ouch!)

- GPX File: Available by contacting us
- More Info: Check out the Mountain Biking Mammoth Book
Turn by Turn (in miles):
0.0 – Start heading up from the trailhead sign (see photo). You’ll quickly pass by a large kiosk with a map. The trail is wide at first, but narrows soon. The climbing is relentless.
.75 – The climbing starts to ease up, but is still tough. You leave the exposed mountainside and head inward a bit. The riding gets a little easier, but the views are diminished.
2.2 – Reach the Ski Area. Here you merge with a wide ski run and descend for a short bit. Look to your left and find the singletrack. Jump on this and start climbing again. This area of the trail is sometimes faint, but more recently has been defined well by rocks, etc.
2.9 – Cross a small creek
3.6 – Reach the Wilderness Boundary. Turn around here and retrace your ride back to the car. Enjoy the sweet trip back – you earned these turns!!

This map from the Mountain Biking Mammoth Book (which was approved by the USFS) shows the Wilderness Boundary very clearly
Ride Report: Lake Canyon Trail – Lundy Lake, CA
This is an ass kicker. No doubt about it. Don’t let the first 1/4 mile of pleasant singletrack fool you. Your legs better be warm, as you climb over 1,600′ in only 3 miles. This is an old 1880’s gold mining road that leads up to May Lundy Mine and Oneida Lake. Much of it has deteriorated to singletrack, and it will get better if more people ride it. In addition to the steep grade, the terrain is rocky and loose in many areas, making the climbing very tough. Of course, the views are impeccable. Right off the bat, you get great views of Lundy Lake and the campground. Eventually you make your way into the glacial valley, paralleling Lake Canyon Creek and eventually crossing over it. Shortly after, you reach Blue Lake and Crystal Lake on your left. We strongly suggest you park your bike at the May Lundy Mine informational kiosk (3 miles) just before the Hoover Wilderness Boundary, and continue hiking to the mine, and Oneida Lake if you like. Reminder – no bicycles allowed past the Wilderness Boundary! There are lots of old mining relics around, and a nice views in all directions. The ride down is a fast, fun, brake burning descent back to your car!
- Ride Type: Out and Back
- Aerobic Difficulty: Short, steep climb is tough on the lungs
- Technical Difficulty: Moderately technical (some rocks and shale)
- Time of Year: Summer and Fall (sometimes late spring – depending on snow pack)
- Terrain/Conditions: A mix of singletrack and doubletrack – some shale/rock gardens – gorgeous high alpine scenery and a historic abandoned mine.
- Access: From the junction of Highway 395 and the 203 at Mammoth Lakes, drive north on the 395 for 32 miles. Exit left towards Lundy Lake. Drive for 3.5 miles and veer left on Lundy Dam Rd. Park at the dam. The ride starts at the gate.
- Length: 6 miles
- Approx. Time: 1.5 – 2.5 hours
- Lowest Elevation: 7,808′
- Highest Elevation: 9,494′
- Total Elevation Gain: 1,665′
- Bike Recommendation: This can be ridden with pretty much any off-road bike, but a lightweight/ full suspension xc bike is ideal.
- GPX File: Available by contacting us
Turn by Turn (in miles):
0.0 – Go past the gate and ride up to the informational kiosk. After reading, head left on the singletrack. Get ready to climb!
2.0 – Cross the creek, and enjoy a short section of flat riding. This is a great spot to take a break.
3.0 – Reach the May Lundy Mine informational sign. Although the actual Wilderness Boundary is 0.2 miles past here, this is where we park our bikes and hike up to the mine. Walk ahead, and veer right in 0.1 mile and start climbing (going straight will take you to a dead end and an arsenic warning sign). Once you reach the main mine shaft, you can continue hiking up to Oneida Lake as well. Eventually, make your way back to your bike and start the descent.
6.0 – Reach the dam gate, end of ride.
Ride Report: Silver Canyon Ride – Bishop, CA
The Silver Canyon Ride has an average 13.7% grade, and is one of the most brutal climbs in the area. It’s on par with the Laurel Lakes Ride in terms of climbing treachery. It’s also the first/toughest part of the White Mountain Epic. After parking at the Laws Museum, engaging in nervous small talk, and applying ample chamois cream, you saddle up. A peaceful climb eases the nerves and warms the legs. You are cruising up the famous Silver Canyon Rd. After not too long, that elementary climb turns into a grueling effort that has your lungs puffing out of your chest like Lou Ferrigno. From 4,000′ to 10,800′ over 11.6 miles we go. Silver Canyon is a grueling rite of passage climb. Make sure your brake pads are fresh and your wits are perky. The Silver Canyon descent is FAST and DANGEROUS. Especially when you’re fatigued. When it was raced in 1986 as the Plumline Ultimate Kamikaze, they put nets and barricades up around the dangerous turns to keep people from flying off the mountain. There were also ambulances at the ready, and yes, they were necessary. There will be no ambulances, no barricades, nothing. So BE WARNED. Read Alan’s blog on Silver Canyon for a personal account of riding this trail, and the White Mountain Peak Challenge blog which has a ton of info and photos of Silver Canyon as well.
Note: Much of this ride is very remote. Please be self-sufficient and carry plenty of water and nutrition as well as items to fix your bike in a jam. Weather frequently changes as well, so be ready for anything!!
- Ride Type: Out and Back – as described here
- Difficulty: Advanced climbing and descending skills required. Have fresh brake pads for the descent!

- Length: 22.6 miles total (11.3 miles each way)
- Approx. Time: 3-5 hours, maybe more depending on skills and comfort level
- Lowest Elevation: 4,114′
- Highest Elevation: 10,504′
- Total Elevation Gain: 6,483′
- Bike Recommendation: Lightweight XC mountain bike is best. Full suspension or hardtail.

Turn By Turn (in miles):
No turn by turn directions necessary here. Simply climb up Silver Canyon Road. Stay on the main road and don’t take any spur trails that might pop up. You’ll do about 8 creek crossings and pass a gate around 8 miles in. Then it gets really steep with a bunch of switchbacks. Keep trucking until you reach White Mountain Road at 11.3 miles. Turn around and head back to your car at Laws. Pat self on back.
Ride Report: Sand Canyon Trail near Mammoth Lakes, CA
Sand Canyon Mountain Bike Trail is a gem that often gets overlooked by the nearby Lower Rock Creek Trail. The trail is accessed from Rock Creek Lake. After a tough 500′ climb over 1.3 miles, you reach the official trailhead. This is some of the highest mountain bike riding in the Eastern Sierras. From here, it’s pretty much a bomber 4,000′ descent with great views in every direction. It’s mostly jeep road, and very sandy at times, some creek crossings thrown in. There’s one or two tough climbs, but mostly it’s, down, down, down. It will definitely put a grin on your face. If you’re in the mood to explore and climb more, you can take the Wheeler Crest Out and Back about 4 miles into the ride. You can also include the Swall Canyon Trail, Wagon Wheel Trail, and the above mentioned Lower Rock Creek Trail for an epic day in the saddle. The most popular way to do Sand Canyon is by shuttling it (as described here). However, hard core riders can choose to do the Sand Canyon Loop, including the 4,000′ pavement climb up to Rock Creek Lake. There is also a way to get to the top of Lower Rock Creek Trail via dirt.
If you have questions about any of this or tailoring a ride to suit you, send us a note. Note: Much of this ride is very remote. Please be self-sufficient and carry plenty of water and nutrition as well as items to fix your bike in a jam. Weather frequently changes as well, so be ready for anything!!
