Mammoth Cave National Park trip planner

Mammoth Caves National Park is the longest cave system in the world so far discovered. Spelunkers have explored over 644 km (400 mi) of passageways and periodically add to this total. Tours bring visitors into the massive chambers, rooms with stalactites that resemble a waterfall, and passageways where humans left signatures with candles up to 200 years ago. Electric lights illuminate many areas, but tours by paraffin lamp and guided visits into undeveloped areas of the caves present a new way to explore them. This park, however, isn't just about the caves; the hilly terrain and rivers above offer hiking, biking, horseback riding, paddling, and fishing. Situated between the cities of Nashville and Louisville, the park is easily accessible by car. Our United States online vacation planner combines visitor reviews with your personal interests to make an itinerary informed by experts, but tailored to suit your style.
