Mammoth Cave National Park

A national park ranger guiding tourists through Mammoth Cave.

Mammoth Cave National Park is a United States National Park and a UNESCO World Heritage Site in Kentucky's Caves and Lakes region. It preserves the world's longest known cave system, with over 392 miles of caves. The park was established in 1941 and currently draws nearly two million visitors annually.



The cave itself is approximately fifteen million years old. Humans have been visiting the cave for approximately four thousand years, although it was only discovered by Europeans in 1797. Through 1816 the cave was mined for nitrates, used in gunpowder, but after the war of 1812 ended it was sold and cave tours became popular. With nearly two hundred years as a tourist attraction Mammoth Cave is one of North America's oldest tourist destinations.

Flora and Fauna

Mammoth Cave National Park is home to over 70 threatened, endangered or state listed species. More than 130 species are regular inhabitants of the caves. These species are divided almost equally among three classes of cave life: obligate cave dwellers known as troglobites, facultative species which can complete their life cycle in or out of caves (troglophiles), and those that use caves for refuge (trogloxenes). The Park has cave species and biotic cave communities that are among the most diverse in the world. Because of its diverse array of landscapes and habitats, the Park contains an extraordinary 1300 species of plants.

Cave tours

During the summer it is possible to explore a tiny part of the cave without a ranger, but all other areas of the cave require a ranger guide. Besides the year round tours, there are many others that are offered seasonally. It is best to check the park website, or contact the park directly for exact tours offered during your planned visit. In the summer, reservations are strongly recommended as tours sell out quickly, but at other times of year it is usually possible to sign up for a tour when you arrive at the park.

Other activities

The park offers a tremendous number of hiking trails, as well as options for boating, wildlife viewing, and general recreation.



Within the park there is a gift shop at the visitor center, and a store at the hotel offering gifts as well as snacks and basic supplies.


A restaurant is located at the Mammoth Cave Hotel. This is the only public food service within the park proper.

Outside of the park, fast-food restaurants are found in Cave City (McDonald's, Burger King, Kentucky Fried Chicken, Long John Silver's, Taco Bell, Pizza Hut, Dairy Queen), as well as family-style restaurants. More dining options are available in Glasgow located 25 miles east of the park and in Bowling Green located 40 miles south of the park.
