Mammoth Cave National Park
Kentucky
Mammoth Cave National Park in south-central Kentucky protects the world's longest known cave system, with over 426 miles of surveyed passageways. Established in 1941, the park spans over 52,000 acres of forested karst landscape, intersected by the Green and Nolin Rivers. The cave system formed approximately 330 million years ago in thick limestone strata capped by sandstone, creating a remarkably stable environment with unique geological features such as the epikarstic zone and massive sinkholes like Cedar Sink. Visitors can explore a variety of cave tours, including rugged experiences like the Crystal Cave Introduction to Caving Tour, and enjoy over 80 miles of surface trails, river activities, camping, and ranger-led programs. Recognized as a UNESCO World Heritage Site, International Biosphere Reserve, and International Dark Sky Park, Mammoth Cave offers rich biodiversity, extensive human history, and exceptional opportunities for exploration both underground and above ground.
ヒント: Visit during spring to enjoy wildflower blooms and participate in special events like Wildflower Day. Reserve cave tours in advance, especially for limited-experience or rugged tours like the Crystal Cave Introduction to Caving Tour. The park offers accessible cave tours and ranger-led programs for all visitors. Camping and lodging options are available nearby. Check current conditions and alerts before visiting.

歴史
Mammoth Cave National Park was established on July 1, 1941, following complex eminent domain proceedings.
The cave system was formally recognized as the Mammoth–Flint Ridge Cave System in 1972 after a connection was found between Mammoth Cave and the Flint Ridge system.
It gained international recognition as a UNESCO World Heritage Site in 1981 and was later designated an International Biosphere Reserve in 1990 and an International Dark Sky Park in 2021.
The cave developed over 330 million years ago during the Mississippian period, shaped by geological processes in limestone and sandstone layers.
