Natural Tunnel, called the “Eighth Wonder of the World” by William Jennings Bryan, has been attracting sightseers to the mountains of southwestern Virginia for more than 100 years. Today it is the focal point of Natural Tunnel State Park, a park which offers visitors not only spectacular sights but also swimming, camping, picnicking, hiking, a visitor center, an amphitheater and interpretive programs.
