This place is pretty cool. From WI and saw this place on Google. Decided to go day off the Iron Bowl, so it was dead. We were told from locals that it gets cold down in the caverns, but rest assured it's a comfortable 60 degrees. It's a guided tour, you can't touch anything- but plenty of photo opportunities and learning. Highly recommend if you haven't been. Waited less than 5 mins to start. Don't forget to tip your guide (Atticus you rocked!)!
