Penn's Cave — Cavern Tour

Ride a guided boat entirely through one of Pennsylvania's most unusual limestone caverns. Ride a flat-bottom boat through a spring-fed limestone cavern where the entire guided cave tour happens on the water.

This 0.4-mile guided underground boat tour adventure in Penns Valley / Centre Hall is best approached as a real outing, not simply a pin on a map. The experience centers on Penn's Cave — Cavern Tour, with the route and stopping points chosen to make the defining features accessible from the documented public starting point. Allow time to enjoy the setting rather than racing through it.

GETTING THERE & STARTING OUT Drive to 222 Penn's Cave Road and use the attraction's free visitor parking. Check in at the visitor center for the required cavern-tour ticket. Follow the 300-foot paved inclined path and descend 48 concrete steps to the dock. Board only when directed by staff and remain with the guided boat tour through the cave. After the boat portion, use the same stairs and inclined path to return to the visitor center. Your documented starting point is Penn's Cave Visitor Center Parking. Use that access rather than navigating directly to a scenic feature, which may not have legal parking or a public approach. For driving navigation, the recorded destination is Penn's Cave & Wildlife Park, 222 Penn's Cave Road, Centre Hall, PA 16828.
