Mammoth Cave National Park
Mammoth Cave National Park in Kentucky protects the world’s longest known cave system, a vast limestone landscape shaped by water and recognized for its geological features and cave wildlife.
Location and cave system
Mammoth Cave National Park is in Kentucky, United States. The National Park Service reports that explorers have surveyed and mapped more than 426 miles of passage in the cave system, which remains under exploration. UNESCO describes Mammoth Cave as the world’s most extensive cave system and notes its characteristic limestone formations.
Geology and ecology
The cave passages formed as underground rivers and streams dissolved and carved the underlying limestone over millions of years. UNESCO identifies karst features including underground conduits, sinkholes, fissures, rivers and springs in the surrounding landscape. The cave also supports varied wildlife, including species adapted to life underground; UNESCO’s World Heritage assessment describes more than 130 cave-dwelling species.

The park was established on July 1, 1941, to preserve its cave systems, river valleys and surrounding hill country, according to the National Park Service. UNESCO inscribed Mammoth Cave National Park on the World Heritage List in 1981, recognizing its exceptional cave formations, geological record and wildlife.
