Welcome to CBMBA—the oldest mountain bike club on the PLANET! Since 1983 CBMBA has been creating, maintaining, advocating for, and putting mad love into 450+ miles of singletrack around Crested Butte.

CBMBA works to improve trails, conserve landscapes, and build community through volunteer trail work days, group rides, events, and a professional trail and stewardship crew, the Crested Butte Conservation Corps (CBCC). All trail users benefit from the work that CBMBA does. Help us build and maintain sustainable trails and conserve the landscapes around CB by making a donation, becoming a member, volunteering, or attending an event. 

Want to learn more about the summer and winter trails around CB? Check out the “Conditions” (summer) or “Grooming Report” (winter) and peruse the rides for ways to link the trails into epic loops.



April 29, 2021 Update

A few trails are rideable in the Crested Butte and Cement Creek areas. See details on CBMBA's Conditions page.

If you're looking for bigger rides and more variety, head to Hartman Rocks in Gunnison, as the majority of CB's trails are still covered in snow or are very muddy.
