Hawaii trails · Munro Trail
A 12.3-mile out-and-back in Hawaii, with 2,138 ft of climbing. Reaches Puu Aalii and other summit/viewpoint destinations.
The climbing leans toward the middle third: 45% of the ascent falls between mile 4.1 and mile 8.2. It gives back about 1,758 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 5:48 a.m., the sun rises at 6:11 a.m. and sets at 6:44 p.m., and the last usable light fades about 7:06 p.m. (HST) — 12 h 33 min of daylight. At about 2.7 mph plus 30 minutes per 1,000 feet of climbing, the 24.6-mile round trip takes roughly 11 h 15 min, so leaving the trailhead at sunrise puts you back around 5:25 p.m. — 1 h 19 min before sunset.
