"Such a joy and wonder! These Caverns are so so amazing! Make sure you ask for a tour with Mr. Seal, who is so very knowledgeable plus funny! Even in the darkest and scariest parts of the caves, there is so much natural beauty to experience and enjoy. Mr. Seal makes sure everyone is safe and well-educated about all of the beautiful colors, sparkles, shapes, and 'nature walls' that we see! There are some 'ooh' and 'aaahhhh' moments of wonder and fun surprises in this beautiful cave. Awesome way to spend some of an afternoon!"

"Great experience!!!! Our guide was amazing and knowledgeable! Over 30 yrs! This cavern is beautiful and breathtaking.

"We had a great time here! We went in a small group of 4. I highly recommend joining in with a smaller group, it allows you to easily see all of the beautiful features. If you get cold easily, I also recommend bringing a light jacket, it’s cold underground.
Our tour guide was not only informative, but fun. He took his time at each of the “stops” and made sure we each had time to look and ask questions. Couldn’t recommend this incredible experience enough.
1 thing to note, call to get hours of operation, Google is accurate."
