We really enjoyed the cave tour. Our guide was entertaining and informative, telling us the history of the cave, as well as interesting facts about caves in general. The boat ride across the lake was great too!

Talk about a young, enthusiastic guide. Thomas thoroughly loves his job and was an excellent guide. Kim is in training and let me tell you, she will be just as amazing with such a great trainer. Highly recommend.

Interesting and unique! Wesley was a wonderful and knowledgeable guide for our group. The path and boat ride were fun and not at all strenuous.

It’s what you’d expect. Worth a one time trip, if you don’t have to travel to far. The tour guide was knowledgeable, and very friendly. The gift shop girl was a bit rude.
