New Mexico trails · Animas Divide
A 10.9-mile out-and-back in New Mexico, with 2,543 ft of climbing. Reaches East Curtis Spring and other spring/summit destinations. Managed by the U.S. Forest Service.
The climbing is spread fairly evenly along the route. It gives back about 2,158 ft along the way, so it rolls rather than climbing steadily.

On August 31, 2026 — the day this page was generated — first light reaches this trailhead at 6:19 a.m., the sun rises at 6:44 a.m. and sets at 7:37 p.m., and the last usable light fades about 8:02 p.m. (MDT) — 12 h 53 min of daylight. At about 2.7 mph plus 30 minutes per 1,000 feet of climbing, the 21.8-mile round trip takes roughly 10 h 37 min, so leaving the trailhead at sunrise puts you back around 5:21 p.m. — 2 h 15 min before sunset.
