We were visiting Decorah Iowa and were told about this hidden cave in the middle of nowhere only 30 mins away in MN. It was worth the trip. We have a charming tour guide who made it interesting and fun. It was a beautiful fall day for a scenic drive as well. We made reservations online ahead of time to ensure we got the time we wanted.
