Idaho trails · Center Mountain
A 13.2-mile network in Idaho, with 4,463 ft of climbing. Reaches Center Mountain and other summit destinations. Managed by the U.S. Forest Service.
Most of the climbing sits in the middle third — 60% of the ascent, between mile 4.9 and mile 9.9. It gives back about 3,197 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 6:30 a.m., the sun rises at 7:01 a.m. and sets at 8:20 p.m., and the last usable light fades about 8:50 p.m. (MDT) — 13 h 19 min of daylight. At about 2.7 mph plus 30 minutes per 1,000 feet of climbing, the 13.2-mile route takes roughly 7 h 06 min, so leaving the trailhead at sunrise puts you back around 2:07 p.m. — 6 h 13 min before sunset.
