Mammoth Cave National Park

Mammoth Cave was designated a national park in 1941, and is the world’s largest known cave complex. Comprised of limestone, the cave is still being explored with no end in sight. The park boasts a number of tours to explore the cave’s depths and remarkable features, while also containing a number of above-ground activities and hiking trails. Mammoth Cave was also the site of a number of mining operations during the Civil War prior to its protection.
