Mammoth Cave, the world's longest known cave system

This List of longest caves includes caves in which the combined length of documented passageways exceeds 200 km. In some of these caves, passageways are still being discovered.[1][2]

Geographical distribution[edit]

Caves are found around the world. The largest form in areas of karst landforms whose rocks erode easily. Preferable conditions for cave formation are adequate precipitation, enough plants and animals to produce ample carbon dioxide, and a landscape of gentle hills which drains slowly. The highest concentrations of long caves in the world are found in the Pennyrile of southern Kentucky, United States, in the Black Hills of South Dakota, United States, and in the Yucatán Peninsula, Mexico.
