A 5.3-mile out-and-back in Oregon, with 453 ft of climbing. Reaches Hemlock Lake and other lake/pass destinations. Managed by the U.S. Forest Service.
The climbing leans toward the middle third: 53% of the ascent falls between mile 1.8 and mile 3.6. It gives back about 506 ft along the way, so it rolls rather than climbing steadily.
