"The Hartman Rocks area offers high desert riding in a 6,000-acre basin. Funky granite formations, slickrock, sand, and sage add to this geological curiosity's appeal. The Rocks, as Gunnison locals call it, is a mountain biking area replete with interconnecting trails. This route skirts the perimeter of the Hartman Rocks area and follows, in part, the Rage in the Sage course, Gunnison's annual mountain bike race.
Although the trails throughout Hartman Rocks can get confusing, this shouldn't deter you from riding the "Rocks," as efforts are continually being made to distinguish the right from the wrong way. Take notice of smaller rocks or sticks imbedded in the ground across a trail, signifying a wrong way. The trail rolls over hilly terrain and through sagebrush meadowland. Much of the terrain is hard-packed, but there are a number of rocky and sandy sections. Some sections go through riparian areas. The area offers seemingly endless miles of singletrack and dirt road that break off in every direction."
