Mammoth Cave National Park: The Complete Guide for 2023

New Albany, IN 47150, USA

Mammoth Cave —the longest tunnel cave system in the world—formed over 10 million years ago, but it wasn’t designated as an official US national park until July 1, 1941. The cave earned its name for both the size of its massive caverns and its hundreds of miles of explorable passageways. Within the cave’s 412 miles of explored tunnels, visitors can choose from a variety of cave tours (from self-led to twinkling lanterns to wheelchair and kiddo accessible). Above ground, head to Mammoth Cave National Park for hiking, horseback riding, and camping within the park’s more than 52,000 acres of scenic Kentucky landscape. The Green and Nolin Rivers run through the park, giving guests ample opportunities for canoeing, kayaking, boating, and fishing.

Where is Mammoth Cave National Park?

Mammoth Cave National Park,
Mammoth Cave National Park, Kentucky.

Located on top of the world’s longest known cave system (more than 420 miles of cave passages have been mapped), Mammoth Cave National Park is in south-central Kentucky.

The 53,000-acre park of hills and valleys is located close to Interstate 65. The closest airports are Louisville International Airport (89 miles away) and Nashville International Airport (99 miles away). Public transportation is not an option for reaching the park. Named for the “mammoth” size of its caves, Mammoth Cave National Park is divided by the Green River, which flows east-west through the park’s center. There are no bridges connecting the north and south sides of the park, so visitors can take the Green River Ferry or drive the highways outside the park.

The cave tours and most visitor amenities are on the south side of the river while backcountry camping, hiking, and recreational activities are mostly on the north side of the park.

Over the years, the  Mammoth Cave has been used as a church, wedding venue, and tuberculosis hospital. Today, Mammoth Cave is the world’s longest known cave system, with much more still to be explored.

Because of its steady year-round temperature, a tour of Mammoth Cave serves as a cool retreat in the summer and a warm welcome in the winter. Of course, most of the activities on the 53,000 acres of land above the park are best enjoyed May through September when Kentucky’s temperatures are best suited for being outdoors. Mammoth Cave’s busiest months are June, July, and August.

Today, the remaining steam engines tell the story of life in Kentucky over a century ago. While you won’t find any moving train cars, visitors can still travel by foot or bicycle on the rail path as the abandoned line was converted to the Mammoth Cave Bike and Hike Trail in 2004.
