Penns Cave

What is the headwaters of Penns Creek? Some claim the big river begins some 40 miles west at a spring that once eroded away a massive cavern now known as Penns Cave. First discovered by the Seneca Indians, who according to legend, held ceremonies here, the cavern was first commercialized in the 1800s, and today offers a fun, and educational tour by 30 feet long punts, on the very spring waters that forms Penns Creek.

There’s lots of learn about geology here, and a pretty cool nature areas with local animals to view. It’s definitely worth a visit and a good rainy day excursion, considering that the tour is underground. Bring a jacket. Air temperature in the cavern is a constant 52 degrees, even in the hottest days of summer.
