Lots of fun for kids and adults. An easily accessible cave compared to many caves open to the public. To avoid the most crowded time, go during the week or pick an after-hours tour or one of the first tours of the day on the weekend. Friendly staff and the story of it's discovery is amazing! Get your tickets in advance online because they don't see them at the door. We bought our tickets a few days in advance and by the time we got there that morning, tickets were already sold out for the day.
