Mammoth Cave is a world wonder with over 400 miles of cave and more yet likely still unmapped. Stepping inside the cave will take you back in time and expose you to a level of darkness that is difficult to come by on the surface. After you explore the caves, you can enjoy a nice hike in the park’s Green River Valley, a wonderful showcase of Kentucky’s hill country.
