Kentucky Mammoth Cave

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.

This is the world's longest known cave system, with more than 400 miles explored (365 miles of the five-level cave system have been mapped, and new caves are continually being discovered). Early guide Stephen Bishop called the cave a "grand, gloomy and peculiar place," but its vast chambers and complex labyrinths have earned its name – Mammoth.

Many visitors to Mammoth Cave National Park say, "We just want to see the Cave." But that's only half the story. The park's 52,800 acres feature dozens of unique places to go, whether to the gloomy underworld, the cool and languid river, or the shadow-dappled rolling hills. Mammoth Cave National Park contains more than 70 miles of backcountry trails through forested Kentucky hills for hikers, horseback riders, and cyclists. Several front country trails lead to special places like Cedar Sink, Sand Cave, and Turnhole Bend.

Your exploration of Mammoth Cave will take you to places unlike anywhere you've ever been!

Best time to go – You can visit year-round, as underground, all days are about the same. The temperatures in interior passages fluctuate from the mid-50s to the low 60s.

Where is it - Mammoth Cave, nine miles northwest of I-65, is nearly equidistant (about 85 miles) between Louisville, Kentucky, and Nashville, Tennessee.
