World's Longest Known Cave in Central Kentucky
Getting to Know Mammouth Cave
Mammouth Cave was established as a national park in July 1941. It was created as a way to preserve the cave system, the scenic river valleys of the Green and Nolin Rivers, and a section of the hilly country of south central Kentucky. More than 348 miles of cave have been explored and mapped. Some might say that Mammouth Cave is an international treasure.
