Fauna caves of Illinois. I have been to Illinois Caverns in Waterloo. Illinois Caverns was the only commercially operated cave in Illinios. However, it was recently closed to the public until further notice. It was amazing. I am so glad that I had the opportunity to see the cave before they closed it. You had to have a party of at least 3, a hard hat, at least 3 light sources per person, and sign a waiver.
