New Mexico trails · Mail Trail
A 9.7-mile out-and-back in New Mexico, with 2,064 ft of climbing. Reaches Starkweather Spring and other lake/spring destinations. Managed by the U.S. Forest Service.
The climbing leans toward the first third: 49% of the ascent falls between mile 0.0 and mile 3.2. It gives back about 1,447 ft along the way, so it rolls rather than climbing steadily.
