Utah trails · Notch Mountain
A 20.0-mile out-and-back in Utah, with 1,112 ft of climbing. Reaches The Notch and other lake/pass destinations. Managed by the U.S. Forest Service.
The climbing leans toward the first third: 46% of the ascent falls between mile 0.0 and mile 6.7. It gives back about 2,971 ft along the way, so it rolls rather than climbing steadily.
