California trails · Green Creek
A 10.7-mile out-and-back in California, with 3,133 ft of climbing. Reaches Hoover Lakes and other lake destinations. Managed by the U.S. Forest Service.
The climbing leans toward the first third: 46% of the ascent falls between mile 0.0 and mile 3.6. It gives back about 1,470 ft along the way, so it rolls rather than climbing steadily.
