The Mammoth Cave lies in the “Land of 10,000 Sinks” or the Caveland Corridor, an area in southwestern Kentucky approximately 80 miles south of Louisville. This region is strongly marked by karstic features of all kinds.
With more than 400 miles of passages surveyed so far, the Mammoth Cave is one of the world’s largest known cave systems and was already known to the original native inhabitants of the region by the 1st millennium BC.
This is an incredibly popular attraction for families, and a variety of tours are available. Top attractions in the park include the Mammoth Dome, which is almost 200 feet high, and the Ruins of Karnak, named for its massive limestone columns, which give the impression of a ruined temple.
Other highlights are the Snowball Dining Room, with its extraordinary rock formations; the imposing Frozen Niagara, with its magnificent stalactites and stalagmites; and the beautiful Crystal Lake. All cave tours are ticketed, and hikers should come prepared for the much cooler subterranean temperatures.
Additional things to do in Mammoth Cave National Park include camping, swimming, canoeing, kayaking, bicycling, hiking, horseback riding, and various ranger-led activities for kids.
