Took the Natural wonder tour with a group on a 4H trip. Kids enjoyed the sites, staff was very friendly and tour guide was very good at keeping things interesting for the kids. Overall it was a good experience. Daniel C.
Very neat! If you live in Ohio and haven't seen this, you should definitely put it in your list. It's a little natural wonder with some cool history. The tour guides were pleasant and knowledge, and the gift shop has plenty of knick knacks and stones to choose from. Taylor
