I been to several caves in Pennsylvania & found this only one in Maryland. The history of the cave is interesting & the young girl who was the tour guide was knowledgeable. The only reason I didn't...

Very interesting guided tour round caverns 60 feet underground. Amazing formations. Perhaps not for the claustrophobic.

Excellent tour guide in the caverns, pointing out the various shapes in the formations and explaining the processes that create them. Also explained the history of the caves and their discovery.
