The Spring Hollow Trail is a .28 mile, moderate difficulty hiking trail, that is accessible from a small, marked, parking area off of State Route 646. The trail winds downhill through the woods by way off a narrow, smooth, path that takes users through a hollow and along Stock Creek. The trail brings hikers to the northern entrance of the natural tunnel, the opposite end from the more frequently visited southern opening. The trail ends just inside the tunnel’s mouth and users are well advised to not attempt further exploration. The tunnel has a rich history and has been part of an active railway line since 1890, so trains may approach unexpectedly at any moment.
