I thought the cave was great. I did opt for the creation tour based on the Bible, I would rather take biblical fact over scientific theory any day but that is just me. There are other caves in the area you can go too for the "millions of years" old earth theory. So if that is your thing go there. For me the creation tour was the draw I knew it before I came, and I enjoyed it all.
Great experience.
I took the Waterfall Combo expedition - a five hour adventure into some of the deepest parts of the cave. It was a great experience, and I would absolutely come back to see other parts of the cave. I found it physically challenging, despite being in quite good shape. Good footwear is essential, but be prepared to get dirty/muddy. A small, tight fitting backpack for water and snacks is a good idea, but little else was necessary (I had a light jacket, but took it off half way and just wore a t-shirt).
Or tour guide was very knowledgeable and friendly. Great tour with lots of interesting sites.
The cave itself is very neat and spans 70+ miles total (only 34 miles have been passed through). Lots of history, very cool, open passageways for a quick 1-1.5 hour tour that's only 2.2 miles. Just beware, this is privately owned entrance (the only commercial entrance) and instead of answering scientific questions with actual facts, the guides simply say the fossils are because of Noah's ark and the flood. I knew this going in from other reviews and even saw the poster on the gift shop wall proudly proclaiming this belief. I actually am a spiritual person, however, I am a believer in science and much prefer a different kind of tour;) With all that said, it's still a cool cave so I'm giving it 4. I'd 3.5 were an option, though, it would be that.
A very informative tour, friendly people. Way cool cave.
Challenging walk, slippery and uneven paths. Nice tour though and we did see a few bats.
I wasn't given the option of the Jesus tour like the other reviewer. We just got it. I was appalled. The gave no explanations to my children about the geology and formation of the cave other than it was the result of Noah's flood. And of course that the earth was 6000 years old. It was the biggest load of crap. I would have never exposed my children to such lies had I known that's what it would have been. They can keep their religious ridiculousness. I'll stick to the science.
