Utah trails · Birch Spring-Pass Creek Loop
A 19.8-mile out-and-back in Utah, with 1,088 ft of climbing. Reaches Lake Hollow Spring and other lake/pass/spring destinations. Managed by the U.S. Forest Service.
Most of the climbing sits in the final third — 61% of the ascent, between mile 13.2 and mile 19.8. It gives back about 1,206 ft along the way, so it rolls rather than climbing steadily.
