Colorado trails · Lily Lake Trail
A 11.1-mile out-and-back in Colorado, with 3,303 ft of climbing, topping out at 11,015 ft. Reaches Lily Lake. Managed by USFS Aspen-Sopris Ranger District.
The climbing leans toward the middle third: 50% of the ascent falls between mile 3.7 and mile 7.4. It gives back about 4,377 ft along the way, so it rolls rather than climbing steadily.
