Overview
Mammoth Cave National Park protects the world's longest known cave system, with more than 400 miles of surveyed passageways, nearly twice as long as the next-longest cave system. Established as a national park in 1941 and designated a UNESCO World Heritage Site in 1981 and International Biosphere Reserve in 1990, the park's 52,830 acres in south-central Kentucky are also home to the Green River, which winds through the forests and hollows above the cave.
A guided cave tour is the centerpiece of most visits to the park, giving visitors the opportunity to explore vast chambers, historic passageways, intricate geological formations, and sections of the cave that reveal the park's natural and cultural history.
The National Park Service offers a diverse selection of cave tours ranging from easy walks and accessible experiences to lantern-lit historic tours and challenging off-trail caving adventures. Most tours are ranger-guided and focus on specific themes, including geology, cave history, natural features, and exploration. Visitors can choose tours based on duration, difficulty level, and areas of the cave they wish to explore.
