Mammoth Cave National Park portrait view

The world's longest known cave system lies beneath the rolling hills of southcentral Kentucky, with more than 400 miles of surveyed passageways. Guided tours lead into the underground chambers, home to about 130 forms of life, many of them specialized cave dwellers. Above ground, over 80 miles of trails wind through forests, and the Green and Nolin Rivers offer paddling and fishing. The Mammoth Cave Visitor Center is the place to book tour tickets and plan a trip. Thousands of years of human history are woven into the landscape, from early exploration to historic churches and cemeteries. The park is a UNESCO World Heritage Site and the core of an International Biosphere Reserve.

About the Park

Mammoth Cave National Park, located in central Kentucky, is the longest cave system known in the world, with more than 400 miles of surveyed passageways. Its vast chambers and complex labyrinths have earned it the name 'Mammoth,' not just for its size but also for its intricate and colossal subterranean landscapes. The cave formed over millions of years as water carved through layers of limestone, creating vast rooms, narrow canyons, and unique geological formations. This natural wonder allows us to explore the earth beneath our feet and offers a window into geological time. Visitors to the park can explore a variety of cave tours that range from easy, well-lit paths to strenuous adventures through muddy and less developed passageways. Each tour highlights different aspects of the cave's geology, history, and unique ecosystems, including unusual species adapted to life in the dark such as the eyeless cave fish. Above ground, the park covers over 52,000 acres of scenic hills, river valleys, and hardwood forests, offering hiking, horseback riding, and wildlife watching. Mammoth Cave's human history is as rich as its natural one. The cave was mined for saltpeter, a key ingredient in gunpowder, during the War of 1812, and later it was a popular tourist attraction in the 19th century. The park also includes important cultural sites, like historic churches and cemeteries, which speak to the region's rich cultural heritage. Whether you are marveling at the towering limestone formations beneath the Earth, learning about the cave's role in American history, or enjoying the natural beauty of the Kentucky hills, Mammoth Cave National Park offers an unparalleled experience for all visitors.
