The Moonville Rail-Trail is a sixteen-mile (25 kilometer) rail-trail in southeast Ohio, located in Vinton and Athens Counties. It is largely embedded in the Zaleski State Forest and passes close to Lake Hope State Park. The trail is named after the Moonville Tunnel through which it passes. The governing organization of the trail, Moonville Rail-Trail, Inc., hopes to eventually extend the trail eastward to New Marshfield then to Athens to join with the Hockhocking Adena Bikeway.
