Just to follow up on Cave in Rock, the cave itself is only a few minute walk from parking and is only 100-150 yards deep. Interesting to see but not a lot there. The village of Cave in Rock looks to be straight out of the 1800s, really nothing there since the fluorspar mines closed. The ferry is free to ride over to KY. Garden of the Gods in the same county is neat to see. No gas in CIR but 15 minutes down SR 146 is Elizabethtown with gas and food, there is a floating fish dock that serves the best catfish sandwich you can curl a lip over. When you get in the area contact me and if we're free we may run over, my wife grew up in Cave in Rock. We're 2 hours away.
