Hartman Rocks Recreation Area Directions

From the Town of Crested Butte: Drive 30 miles south on CO 135 and make a right onto Highway 50 in Gunnison. Travel 1.5 miles and turn left onto W Airport Rd. Continue onto Gold Basin Rd for a mile and Hartman’s will be on your right.


Hartman Rocks offers an array of trails ranging from easy terrain green trails to steep, technical, punchy black trails. Numerous maps are laid out across the 8,000 acres of public land. Your adventure can be as long as you want it to be.

Most routes are mountain bike, hike, dirt bike, and trail running friendly. The two track offers a few rocks and creek crossings that will keep you honest. The climb back up from the East River Valley will also prove to be a small but good challenge.


Wildflowers and cactus flourish here in May and June, so bring your camera and soak up the scenery. Horseback riding is permitted and you may run into a couple of riders on the way.  The terrain also makes this a great choice for a run, jog, easy bike ride, and snowshoe, nordic ski, and fat bike in the winter. This is a very dog friendly area, but please keep track of your pooch.
