Ride Report: Uptown / Downtown – Public (Short) Loop – No Bike Park
One of the staples for Mammoth locals and visitors alike. At some point, everyone rides “Uptown – Downtown”. It can either be a great introduction to mountain biking, or an all out lung-buster if you really push it. The version described here is for the “short” loop which goes up to the Earthquake Fault Junction and does not include the portion that enters the Mammoth Mountain Bike Park. You CAN do this ride without purchasing a bike park ticket. If you have a bike park pass/ticket, and you’re looking for a longer loop, consider the Uptown/Downtown Full Loop on the Mammoth Mountain Bike Park Map. Another option is to cross Highway 203 at the Earthquake Fault Junction and continue climbing up Mountain View Trail (a great out and back that is also free to the public without need for a bike park ticket), and then connect back with Downtown. If you’re having trouble figuring out what to ride, or the best way to connect these trails into a ride that suits your style/ability, contact us – and we’ll help you construct a ride that’s right for you!!

Alan's Mountain Biking Adventures
Riding Uptown on snow. There’s a first time for everything.
Have you ever ridden singletrack snow? It’s pretty frickin fun. As mountain bikers, we love the sight of endless ribbons of brown, tacky dirt singletrack (or sometimes white dirt, if you’re riding White Mesa). But guess what? A packed trail of snow, albeit different, can be equally sublime to ride – and just as visually stunning. On either side of you is deep, fluffy snow, and you squiggle your bike through it all. The best of all, is if you fall (actually WHEN you fall – it’s inevitable) – you poof into freshies. What an adventure! It truly brings the vibe of mountain biking to fat biking.
Yes. It is as fun as it looks.
A few of us learned these joys first hand at the Fat Bike Summit last month. We embarked on a group ride up at…
