MP Trail Map: Hartman Rocks

Share this post

Just 30 minutes down the road from Crested Butte, one of the birthplaces of mountain biking, Hartman Rocks near Gunnison is home to terrific, high desert riding that dries out in early Summer.

How to Find it

From Montrose, head east on U.S. 50 toward Gunnison. Approximately 1.5 miles before you get to Gunnison, Turn right onto CR 38 (a.k.a Airport Road). This turns into Gold Basin Road, which you will follow for just less than 2 miles. Turn right onto CR 32C, where you will find a parking lot for day use. If you reach the Iris Road subdivision, you have gone too far.

Where to Camp

Hartman Rocks Campground (see map) Roads in the camping area are dirt, so expect mud in wet conditions. There are 35 sites, first-come, no reservations.  RVs up to 35’ can fit most spots – without hookups.  Pets are welcome. Amenities include potable water, vault toilets, fire rings, and (so you’re not caught off-guard by firearm discharge) a shooting range.



Green: Sea of Sage

Ridden east to west from Road 3570, this 1.5-mile ride is a smooth, flowy singletrack that trends downhill through, you guessed it, a sea of sagebrush. Be ready for some fun curves and dips toward the end.

Green: Evan’s Loop

If you want to double the fun, start in the parking area off of CR 56 near the campground. The first half is a gradual climb through a dry creek bed and around some rock formations. It connects with Sea of Sage to complete the loop. Navigation is well-marked, but you can remember to turn left at each intersection to eventually get back to where you started.

Blue: Josho’s

After a short climb at the beginning of the ride, Josho’s opens up with one of the fastest, flowiest downhills at Hartman’s. Of course, what goes down must go up, so be prepared for a short but steep climb at the end.

Black: Rattlesnake

If your kid is truly looking for a challenging, technical rock moves, check out local’s favorite Rattlesnake. Be sure to ride south to north so the trail trends downhill.
