Colorado trails · Dry Creek Trail
A 15.3-mile out-and-back in Colorado, with 2,980 ft of climbing, topping out at 12,263 ft. Reaches Marble Mountain and other pass/summit/viewpoint destinations. Managed by USFS Divide Ranger District.
Most of the climbing sits in the first third — 56% of the ascent, between mile 0.0 and mile 5.1. It gives back about 2,760 ft along the way, so it rolls rather than climbing steadily.
