Utah trails · Navajo Knobs
A 6.8-mile out-and-back in Utah, with 1,494 ft of climbing. Reaches Nels Johnson Bridge and other arch/viewpoint destinations. Managed by the National Park Service.
The climbing leans toward the first third: 48% of the ascent falls between mile 0.0 and mile 2.3. It gives back about 1,117 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 6:26 a.m., the sun rises at 6:53 a.m. and sets at 7:56 p.m., and the last usable light fades about 8:23 p.m. (MDT) — 13 h 03 min of daylight. At about 2.7 mph plus 30 minutes per 1,000 feet of climbing, the 13.5-mile round trip takes roughly 6 h 31 min, so leaving the trailhead at sunrise puts you back around 1:23 p.m. — 6 h 33 min before sunset.
