Mammoth Cave National Park

Mammoth Cave National Park preserves the cave system and a part of the Green River valley and hilly country of south central Kentucky. Mammoth Cave is the world's longest cave system, with more than 365 miles explored. Cave tours have been offered since 1816, which makes Mammoth Cave one of the oldest tour attractions in North America. While cave tours are the park’s big attraction, there is plenty more to do and explore while visiting this beautiful wilderness area, such as hiking, camping, horseback riding, fishing and kayaking.

Mammoth Cave National Park became a World Heritage Site in 1981 and an International Biosphere Reserve in 1990.
