New Mexico trails · Franz Spring Trail #43
A 10.2-mile out-and-back in New Mexico, with 2,702 ft of climbing. Reaches Franz Spring and other lake/spring destinations.
The climbing leans toward the middle third: 53% of the ascent falls between mile 3.4 and mile 6.8. It gives back about 1,347 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 6:24 a.m., the sun rises at 6:49 a.m. and sets at 7:43 p.m., and the last usable light fades about 8:08 p.m. (MDT) — 12 h 54 min of daylight. At about 2.7 mph plus 30 minutes per 1,000 feet of climbing, the 20.4-mile round trip takes roughly 10 h 16 min, so leaving the trailhead at sunrise puts you back around 5:05 p.m. — 2 h 38 min before sunset.
