Just a stone’s throw south of Gunnison lies Hartman Rocks, a cycling destination that offers an excellent high desert atmosphere for a night beneath the stars. This particular loop is merely one of countless road and trail combinations in the area, each traversing winding roads or singletrack through granite rock formations, seas of sage, and seasonal wildflowers.
Situated within the expansive Hartman Rocks Recreation Area, which spans 14,000 acres, this playground for outdoor enthusiasts sits in the Gunnison River Basin, showcasing views of many of the surrounding mountain ranges, including the San Juans, West Elks, and Sawatch Range. Hartman Rocks boasts 45 miles of singletrack trails and an additional 45 miles of dirt roads. Plus, there are 50 designated campsites and other dispersed camping options within the recreation area.
For those seeking a unique geological and historical sight, the Aberdeen Quarry awaits and acts as a great camp spot. Once hauled from the town of Aberdeen, the gray granite contributed to the construction of notable buildings, including the Colorado State Capitol Building in Denver. The Quarry sits along the South Beaver Creek, providing a refreshing oasis within an otherwise arid and dry landscape, offering a welcomed respite after a few hours in the saddle.
Route Difficulty
This loop is pretty straightforward and offers a nice paved road warm-up followed by some very manageable dirt roads and two-tracks. Only occasionally will you stumble across some technical bits, but they’re nearly always avoidable. The one exception is descending and climbing out of South Beaver Creek, where it’s particularly rocky and steep but relatively short-lived. South Beaver Creek offers water, making sure you don’t need to bring all the water for your trip. That said, if you decided against dropping into the steep valley, you could dry camp in an established campground in the area. There are no resupply points on the route. Between the 15 miles per day, 2,000 feet of vert for the trip, ride surfaces, and elevation, this route has a difficulty rating of 3 out of 10.
If you decide on the singletrack version (see Trail Notes tab below), you will undoubtedly be in for more challenging terrain with technical singletrack trails that add up, which makes for about the same daily mileage with more vertical. Give yourself more time if you select the singletrack route. The singletrack route has a difficulty of 6 out of 10.
Route Development: I have been going to camp out at the Quarry ever since I went to school at Western State Colorado University. It’s a great spot with several different camping options that are difficult to get to in a car. My first time bikepacking out here was on the singletrack version. It’s about the same mileage but certainly more challenging mile per mile. Hartman Rocks is a great place to camp. Whether it’s on the north side of the recreation area near the trail heads or all the way down to South Beaver Creek, you’ll enjoy varied views and perspectives with every turn.
If you want to tack on more singletrack, you can drop your bags and make the Aberdeen Loop, a fantastic nine-mile loop that starts and ends at South Beaver Creek.

- Other wildlife is abundant such as mountain lions, deer, antelope, rabbits, and chipmunks.

- Camping north of the power lines in Hartman requires staying in established campgrounds, which are first come, first served. This also means you will not have access to water, but if you plan ahead, these sites offer some really unique camping experiences.
- The established camping spots can be popular on weekends during spring and fall, so plan ahead and have a backup plan.
- South of the power lines is open to dispersed camping. However, make sure you camp on BLM land. If you want to camp near the quarry, this requires you to camp south of Beaver Creek.
