5 /5 Jessica Toy: This was a different local outing in Polk County. It was very interesting and fun to explore. Make advance reservations through their website. The tour was closer to 2 hours with some extra time to wander the grounds afterwards, so I’d definitely budget a little extra time at the end there. The guide was great and knowledgeable. I did have my young kids (6 and 10) with me. I would say that everyone was friendly to them, including the guide, but they were not very interested in the tour. If I were to do this again I would leave them at home lol
