West of Green River, the Devils Racetrack Trail is an multi-use track in the San Rafael Swell that is open to dirt biking. Altitude change is 1200 feet, but some up-and-down riding makes total climbing about 1700. As an out-and-back, the round trip is 17.6 miles. This trail features awesome views -- down into the Devils Racetrack, out over the San Rafael, and up at the giant stone monoliths. The trail flirts with the edge of the Devils Racetrack, a sheer 300-foot chasm formed by cliffs of Wingate sandstone. As you follow the downsloping Kayenta, youll pass castles and spires of Navajo Sandstone
