Idaho trails · Owyhee Uplands Backcountry Byway
A 100.9-mile point-to-point in Idaho, with 3,777 ft of climbing. Reaches Peppermint Spring and other lake/spring destinations. Managed by Various.
Most of the climbing sits in the first third — 60% of the ascent, between mile 0.0 and mile 33.6. It gives back about 4,526 ft along the way, so it rolls rather than climbing steadily.
