Don’t miss this cave

We just loved the cave and our guide. Totally fascinating. The number of steps they highlight is not too bad, as they are spread out. Guide was informative and patient- allowing us enough time to take in this amazing place. Also loved the selection of stone artifacts and items in the gift shop.

we loved it

There were a lot of interesting features in this cave (fossils, echo chamber, waterfall, spring, etc) ! It had a little bit of everything. I think my favorite was the purple phosphorus deposits and how it absorbed the UV light & glowed. It was fine for our 8 year old and I carried the 4 almost 5 year old down a couple of the staircases just so we were not going too slow but the 4 year old did a lot of it herself also.

Unique experience

We had such a fun time and would do it again. Our guide was very nice and patient with our four year old. He even offered him a flashlight which was the highlight for him. The stairs make for a nice little workout at the end.

Interesting and fun activity

Really interesting activity that I high recommend. Our tour guide was excellent. As mentioned, there are a number of stairs to climb, especially when leaving the cave at the end of the tour.
