Summary: This was such a neat experience! The walking tour was very informative and the scenery so cool! So much to look at with the stalagmites and stalagtites! We are not in the best of shape and was able to tackle the Discovery tour with no problems. If you struggle with inclines, it may not be for you.

Summary: The caverns were amazing. We have been through a few caverns but this one is by far the most beautiful. The only downfall is that if you are not in the best health it can be a tough walk. There are a lot of inclines to walk walk up so be prepared.
