Discover America's Only All-Water Cavern
Step aboard a guided boat tour and journey through America's only all-water cavern. For 45 unforgettable minutes, you'll glide past spectacular limestone formations, towering columns, and centuries of natural history while learning about the geology and legends that make Penn's Cave one of Pennsylvania's most remarkable natural attractions.
A 45 minute fully-guided tour of the all-water cavern—entirely by boat!
Penn’s Cave, the only cave in Pennsylvania on the National Register of Historic Places, features glittering stalactites and stalagmites, often in mysteriously familiar shapes, such as “The Statue of Liberty” and “The Garden of the Gods.” See how dripping water has sculpted magnificent flowstone, curtains, cascades, and draperies against a background of pillars and gigantic columns.
What to Expect
Glide through our all-water limestone cavern on a fully guided flat-bottom motorboat tour. The flat-bottom motorboats accommodate 22-24 persons. There are 48 steps leading to the cave’s main entrance, which is not handicapped accessible.
We recommend bringing a jacket or sweater, as the inside temperature of the cave remains 52 degrees F year ‘round! Comfortable walking shoes are advised. Photos are permitted.
Accessibility
The cave tour is considered strenuous and is not accessible – there are 48 steep concrete steps that lead to the dock entrance where the tour boats are boarded. There are handrails on either side of the stairs. There is also a 300 foot paved steep inclined path that leads to the staircase. The same stairs and path are used to return to the Visitors Center following the tour.
