Ash Canyon Trail runs 2.89 miles near Jerome, in the Verde Ranger District of Prescott National Forest, as trail number 0539. The typical grade is 12 to 20 percent. That is steep, and on a canyon route it usually means the climbing comes in long pushes rather than spread out evenly. The tread is native material; the class is 2. Hiking, horses and bicycles are the listed uses, though a grade this steep is hard work on a bike in at least one direction. Trailhead directions and water information are not posted for this trail, so plan from the district office before you go.
