Mammoth Cave National Park – Tours, Camping, and Best Tips

Petr Novák

Mammoth Cave National Park in Kentucky conceals a unique world – the longest cave system globally with 398 mi of surveyed passages. The second-largest cave system, Sac Actun in Mexico, is less than half as extensive. Mammoth Cave, continuously expanded by new discoveries, is so extraordinary that it has been included in the UNESCO World Heritage List.

Information About Mammoth Cave National Park

Mammoth Cave National Park, located near Brownsville, Kentucky, is about an hour and three-quarters drive from Nashville. Spanning 83 mi2, it is one of the smaller parks. However, this is not surprising given that the vast majority of it is underground. Mammoth Cave receives approximately 515,774 visitors annually, as per 2021 statistics.

Mammoth Cave National Park was established on July 1, 1941, but the area was already quite active before that. During the Anglo-American War of 1812, the caves were used as a nitrate source needed for gunpowder production. The source was guano – accumulated bat droppings. Due to the British blockade, there was a severe shortage, and Mammoth Caves emerged as a suitable source. Joseph Bishop, an African-American slave serving the caves’ then-owner, Franklin Gorin, extensively mapped the caves in the 1830s-40s.

In 1972, Mammoth Cave and Flint Cave, then the world’s longest cave, were connected.

As is typical with caves, bats primarily populate them. In Mammoth Caves, the most common bat species include the brown bat, the yellow bat, and the social bat. The combined population of these species in the historical part of the caves is estimated to be in the thousands. In addition, the watchful eye can spot newts, spiders, and the endangered cave shrimp.
