Discover the most magical spots to pitch your tent or park your rig on your next Natural Tunnel State Park adventure.
As tall as a city high rise, this natural cave has been attracting sightseers for over 100 years.
This natural tunnel was called the Eighth Wonder of the World by William Jennings Bryan. Standing at 10 stories tall, the geological wonder formed over a million years ago. Groundwater bearing carbonic acid percolated up through the limestone, slowly dissolving it. A creek diverted into this underground chasm, further eroding the rock to form the tunnel you see today.
The natural cave is so large, it has served as an active railroad tunnel since 1894. On the 3rd Saturday of every July, the trains stop, allowing park visitors to walk through the 850-foot long tunnel. On other days, you can take a chair lift down to the viewing area at the bottom of the gorge.
The surrounding 900-acre park is great for hiking in solitude. For a stunning view, climb Lovers Leap Trail to the scenic overlook 300 feet above the gorge. Two campgrounds offer sites with electric hook-ups and access to the pool. But the large cabins are awfully tempting, as are the adorable yurts constructed in 2017.
The best time to visit Natural Tunnel State Park is from May through October, when the chairlift operates and full access to the tunnel is available. Winter offers a unique, serene beauty, but some facilities may be closed, and the chairlift is not operational.
