The Commonwealth of Virginia acquired the tunnel and 100 surrounding acres in 1967 from the Natural Tunnel Chasm and Caverns Corp. to establish Natural Tunnel State Park. Approximately 750 additional acres were later acquired and the park opened in 1971.
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.
The creation of Natural Tunnel began more than a million years ago in the early glacial period when groundwater bearing carbonic acid percolated through crevices and slowly dissolved surrounding limestone and dolomite bedrock. Then, what is now Stock Creek was probably diverted underground to continue carving the tunnel slowly over many centuries. The walls of the tunnel show evidence of prehistoric life, and many fossils can be found in the creek bed and on tunnel walls.
Daniel Boone was probably the first white man to see the tunnel. However, no one wrote of it until Lt. Col. Stephen H. Long explored the site in 1831 and published an article in a geology journal in 1832. The areas near the tunnel were mined for saltpeter during the Civil War. In 1890 the South Atlantic and Ohio Railroad arrived and, making use of the natural formation, laid tracks through the tunnel. In 1906 Southern Railway acquired the tracks and created a passenger line, the Natural Tunnel Line, that went through the tunnel. Large coal deposits were discovered in the area shortly thereafter, and although they no longer carry passengers, trains continue to this day to carry coal through Natural Tunnel.
Complex includes a 5,400-square-foot pool, a large bathhouse, and a snack bar in the concession building. The pool opens daily Memorial Day weekend through Labor Day from 10 a.m. - 6 p.m. on weekdays and from 10 a.m. - 7 p.m. on weekends. In the summer, swimming is free for overnight guests in campsites, however it cannot be guaranteed should circumstances beyond the park's control require that swimming be closed. We do not give refunds for swimming to overnight guests under any circumstances.
