On August 31, 2026 — the day this page was generated — first light reaches this trailhead at 5:56 a.m., the sun rises at 6:48 a.m. and sets at 9:20 p.m., and the last usable light fades about 10:11 p.m. (AKDT) — 14 h 32 min of daylight. At about 2.7 mph plus 30 minutes per 1,000 feet of climbing, the 14.5-mile round trip works out to roughly 17 h 49 min of walking — more than a single day of daylight here, so plan it as an overnight or hike it in sections.
