I expected a hokey experience with minimal geologic formations. So I was pleasantly surprised as that was not correct. The spaces were tight, so it may not be advisable if you are large or claustrophobic. Frankly if you have mobility issues it wont be a good idea. Also the proximity in tight spaces mean your co-visitors' personalities is important to the enjoyment. I was surprised to pay $20 for something I had never heard of before. The price seems high but it was the real deal. Much smaller scale than Luray though.
