Washington trails · Hidden Lakes
A 21.6-mile point-to-point in Washington, with 1,842 ft of climbing. Reaches Eightmile Pass and other lake/pass destinations. Managed by the U.S. Forest Service.
The climbing leans toward the middle third: 45% of the ascent falls between mile 7.2 and mile 14.4. It gives back about 2,998 ft along the way, so it rolls rather than climbing steadily.
