Missouri trails · Opossum Hollow Trail
A 6.7-mile out-and-back in Missouri, with 142 ft of climbing. Reaches Sullivan Lake and other lake destinations. Managed by the state.
The climbing is spread fairly evenly along the route. It gives back about 370 ft along the way, so it rolls rather than climbing steadily.
