***** (5 stars)
This cave may not be filled with spectacular stalactites and other formations, but it is rich in history, since it is the cave from the Tom Sawyer novel (and four other Mark Twain books). Walking through its labyrinthian passageways really brings the book into focus, and the guides do a great job of identify various locations mentioned in the book.
It’s a very easy cave to traverse, with flat floors, no steps, and no climbing. It’s also a cool 52 degree respite on a hot summer day, so bring a jacket!
