District of Columbia trails · Valley Trail
A 2.4-mile out-and-back in District of Columbia, with 154 ft of climbing. Reaches Pulpit Rock. Managed by the National Park Service.
Most of the climbing sits in the first third — 63% of the ascent, between mile 0.0 and mile 0.8. It gives back about 255 ft along the way, so it rolls rather than climbing steadily.
