It's overpriced and not educational. Compared to other caves, these caves are below average. The tour guide insulted disabled people on the tour. He wouldn't wait for people at the back of the tour to catch up. He wouldn't let people take pictures. He made fun of curious school-aged children. It was horrible! more

Visited NBC today with our daughters, ages 10 and 13. They have been to Carlsbad, so I was worried. But they loved the smaller tour, with the ability to interact with our tour guide and ask questions. We took the COMBO tour. The Illusions tour is more fun and a more amazing cave, but it is lots of climbing and... more

I added the caverns to our vacations itinerary driven by the reviews in TripAdvisor, but this time I am disappointed. I am from Mexico and have been to Cacahuamilpa Caves in Guerrero; those are caves, huge caves where a small building could fit in and great formations. In Natural Bridges, the tour guide announced we were passing to "the Cathedral",... more

This is a great attraction. Look for coupons. The tour guide was good. The only thing I would suggest is keeping the group sizes smaller. We had a LOT of people in our tour group which made it rather crowded in those tight places and hard to get pictures sometimes. Other than that, the tour was very good. Would do... more

The caves were good. Things to watch out for there is a lot of walking, up and down stairs and it can feel a little stuffy. The exercise with the heat may not be good idea for a lot of people. My two sons are 4 and 7 and they enjoyed seeing the formations and their most favorite thing to... more

I'd been to WonderWorld in San Marcos several years ago, and we stopped in here with our kids (10 and 14) while on vacation in July. I thought I remembered the caverns being cool, but they aren't. I was pouring sweat until I got back outside in the breeze. We did the combo tour, Discovery and Illumination. I liked the... more

Since it was our first time here, my wife and I did the basic discovery tour. This was a 70 minute guided tour through one section of the caves. The walking involved is very slippery and you need to be in decent shape since there are a number of stairs and hills to walk up and down. There are many... more

OK its been about 7 years since ive been. I was still in school. Any cavern is a must see. This one did seem to feel a bit slippery when walking on a few steep slopes, but noone slipped. Go to the one in Missouri too! more

Natural caverns. Very impressive! Lots of interesting but unlevel walking so be sure to wear comfy shoes and dress casual. Absolutely beautiful sites to be seen. Guided tour is 75 minutes but more due to waiting for group to catch up than length of tour. Tour guide very knowledgable and friendly. Temp in cavern is around 70 degrees with 99%... more
