Hartman Rocks is a large trail system just outside the city of Gunnison. There are more than 50 miles of mountain bike trails stretching over the rolling hills of rocky terrain. Trails at Hartman’s range from beginner to expert. Most trails are a mile long or less and can be easily linked to others to create a ride of any length. In addition to mountain biking, this popular recreation area is open to hiking, camping, climbing, OHV and shooting. 

There are hundreds of miles of bike trails surrounding the town of Crested Butte. Some trails, including the Lower Loop trail system, are able to be ridden to right from downtown. Or, drive up any Gunnison National Forest road, including Slate River, Washington Gulch or Gothic, and you’ll find MTB trails. There are large swaths of trails to be found south of Crested Butte, including off Brush Creek Road and Cement Creek Road (near CB South). There are too many trails to name here, so we’ve created a map so you can find the trails that suit your ability level and transportation capabilities.

Gunnison Trails and Crested Butte Mountain Biking Association—the oldest mountain biking club in the United States—are the two local trails organizations that build and maintain the Gunnison Valley’s mountain bike trails and educate locals and visitors alike about land stewardship.

While enjoying our trails on your Colorado mountain biking vacation, please consider supporting these hardworking volunteers who care for our treasured public lands.
