This is the entrance to America's ONLY all water cavern.
You go through the tunnel entrance on an hour tour by motor boat.
On the other side is a 1500 acre wild life farm.
Penns Creek which flows below us is a large,
feritle, limestone stream that arises from
Penns Cave, going 81 miles to it's confluence with the Susquehanna River.
It is the longest all spring fed creek in Penna.
