Arizona trails · Highline
A 13.3-mile out-and-back in Arizona, with 1,593 ft of climbing. Reaches Miller Spring and other spring/waterfall destinations. Managed by U.S. Forest Service.
The climbing leans toward the final third: 48% of the ascent falls between mile 8.9 and mile 13.3. It gives back about 2,941 ft along the way, so it rolls rather than climbing steadily.
