Natural Tunnel State Park
Duffield, VA

Park Size: 950 acres. The tunnel is 850 feet long and 100 feet high inside.

Daniel Boone was probably among the first men of European descent to see the tunnel in that the tunnel lies along the original route he took westward. 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, which 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.

Hiking, mountain bike and self-guided trails - Natural Tunnel State Park has seven walking trails. The longest is 2.1 miles long. The trails lead to unique features of the park: the tunnel floor, Lover’s Leap, Tunnel Hill and Gorge Ridge. A 500-foot boardwalk and observation deck provide accessibility to guests with disabilities who may ride the chairlift, when operable, to the mouth of the tunnel. Most trails are open to mountain bikes.

The visitor center is open daily and provides with information on the park and its programs along with the surrounding area’s attractions. The facility has restrooms available for public use and a gift shop and exhibits on the history and geology of the park there.

The Wilderness Road Blockhouse and Visitor Center, an interpretive area next to the park's picnic area, illustrates the role the blockhouse played in the 1700s during westward expansion of the nation. Hours vary so please call the park for specific dates and times. The park lies along the Daniel Boone Wilderness Trail driving tour
