Recommended Users: Mountain Bikers, Hikers. Singletrack trail. .8 miles in length. Difficulty: Moderate/More Difficult. The Precipice Trail starts on the left about 50 feet from the trailhead stepover off the Barrel Roll Trail. It connects to the Sidewinder Trail and can provide an alternative route for the lower section of Barrel Roll. Although it sits just below Barrel Roll, Precipice offers different terrain, plants, and views. Sitting on a bench that receives a southern exposure, barrel cactus and hedge hogs are more prevalent here than on the lower section of Barrel Roll. Views of Cove Wash and the adjacent mesas are also more easily seen from the trail.Precipice is so named because of the tight squeeze that occurs in the middle section of the trail. Hugh rocks slabs tumble down the slope from the upper rim and pinch the trail against a lower cliff edge. While trail construction has moderated the technical aspects of the trail, exposure is still a factor.
