California trails · Alger Lakes
A 9.6-mile network in California, with 3,162 ft of climbing. Reaches Gem Pass and other lake/pass/viewpoint destinations. Managed by the U.S. Forest Service.
The climbing leans toward the first third: 48% of the ascent falls between mile 0.0 and mile 3.2. It gives back about 1,617 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 5:58 a.m., the sun rises at 6:25 a.m. and sets at 7:27 p.m., and the last usable light fades about 7:54 p.m. (PDT) — 13 h 02 min of daylight. At about 2.7 mph plus 30 minutes per 1,000 feet of climbing, the 9.6-mile route takes roughly 5 h 09 min, so leaving the trailhead at sunrise puts you back around 11:34 a.m. — 7 h 53 min before sunset.
