Colorado Mountain Biking Opportunities: Hartman Rocks Trail

Hartman Rocks is a popular mountain bike area just a few miles southwest of Gunnison, Colorado, providing a true backyard to backcountry riding experience. Trails within this system provide a range of opportunities for all skill levels. There are plenty of natural technical slickrock features intermixed with traditional single track trails and natural surface roads. All trails, except a few serious downhill trails, provide for two way traffic creating a new experience each time you ride. Views at Hartman Rocks are spectacular especially during sunrise and sunset with the Gunnison Basin to the North and the San Juan Mountains to the south.

Roads and trails are closed south of the Powerline Road from March 15-May 15 for Gunnison Sage-grouse conservation.

One of the Bureau of Land Management's "Backyard to Backcountry" treasures, information on the  Hartman Rocks Trail was developed between IMBA and the Gunnison, CO, BLM office to provide world-class riding experiences. IMBA's data on the trail includes elevations, ratings, current conditions, photos, and comments.
