Natural Tunnel State Park
More than 850 feet long and as high as a 10-story building, Natural Tunnel was naturally carved through a limestone ridge over thousands of years. William Jennings Bryan called it the “Eighth Wonder of the World.” Other scenic features include a wide chasm between steep stone walls surrounded by several pinnacles, or chimneys.
Facilities include a campground, picnic areas, amphitheater, visitor center and gift shop, historical blockhouse, swimming pool and chair lift to the tunnel floor. The park also offers cave tours and canoe trips on the Clinch River, as well as the Cove Ridge Center, which offers environmental education, conference facilities and overnight dorm accommodations.
