A 12.4-mile out-and-back in Washington, with 2,706 ft of climbing. Reaches Bear Pass and other lake/pass destinations. Managed by Gifford-Pinchot National Forest.
Most of the climbing sits in the middle third — 59% of the ascent, between mile 4.1 and mile 8.3. It gives back about 2,049 ft along the way, so it rolls rather than climbing steadily.
