On October 14, 2026 — the day this page was generated — first light reaches this trailhead at 6:42 a.m., the sun rises at 7:08 a.m. and sets at 6:28 p.m., and the last usable light fades about 6:54 p.m. (MDT) — 11 h 20 min of daylight. At about 2.7 mph plus 30 minutes per 1,000 feet of climbing, the 22.4-mile round trip works out to roughly 12 h 28 min of walking — more than a single day of daylight here, so plan it as an overnight or hike it in sections.
