Some more info
This is an old thread, but more info. Mammoth Cave is a great adventure. Great park. But as said Big.. Real Big Park. Been there several times. They offer several different tours of the cave. Some you walk and stand the whole way, others you get down and get dirty. Some 2 or 3 hour tours and some 1/2 day or more tours. I think it's a great place to take a kid. Stay and camp and enjoy the area. Bring bikes if you can, kayaks or canoes, great river. If you have kids and the Six-gun mountain park is still open, visit it, rides and western shows, great day trip then back to camping. If I remember right about 10 miles North of the Mammoth Cave exits. Also they just opened a Dollar store right next to the Park City exit. When I brought the kids there many years ago, not a lot of "value" priced places to get food at that time. Also golf and shooting range in the area.
