We decided to check out Mammoth Caves figuring it was a big cavern, wrong. It is a VERY big cave, but not a cavern.
There are several different hikes / tours you can take. We choose one that was about 2 hours long which was fine time wise.
The caves are deep, dark and a bit of a challenge to walk. Well the one we did was, but they do offer tours for just about anyone.
