We recently visited Mammoth Cave on the our trip to Louisville. I'd recommend reserving your tour ahead of time. It is free to get into the park & there's quite a bit of hiking around it, but it costs to go on the tours. Click here to learn about the tours & make your reservations. We did the Dome & Dripstone tour. It was a good combination of history & beauty. It's not for those that are claustrophobic.
