Underground Wonders: Kentucky’s Mammoth Cave with Kids

Mammoth Cave National Park is a great place to visit with kids. The cave itself is huge, the largest known cave system in the world, with explorers mapping more passageways each year. Kids will love going deep into the dimly lit (and sometimes dark!) cave and learning all about the history and geology of the cave. With so much to see and do, a visit to Mammoth Cave with kids is the perfect destination for a family vacation.

Mammoth Cave National Park also offers a wide range of ranger-led programs and outdoor activities from camping and hiking, biking and boating, to backcountry camping and horseback riding. Don’t forget to get Junior Ranger badges!

What is Mammoth Cave National Park Famous for?

Mammoth Cave National Park is home to the world’s longest-known cave system. Primarily made up of limestone, this labyrinth contains over 400 miles of explored tunnels and it is estimated that there are at least another 600 miles more that have yet to be explored.

Mammoth Cave National Park encompasses Mammoth Cave and a number of other smaller caves. The park was established as a National Park in 1941 to preserve the cave system for future generations. The caves are also a popular destination for spelunkers or people who explore caves.

The climate inside the caves is relatively stable, and the environment is protected from outside weather conditions. As a result, Mammoth Cave has become one of the most popular tourist destinations in Kentucky.

Unlike other famous cave systems, you won’t see many dripping and delicate stalactite or stalagmite structures. Rather, you’ll find a dynamic history of different groups using the cave in different ways, and the stories that accompany them.

Don’t miss our posts on other US National Parks & Monuments– we’ve loved exploring them as a family with our National Parks Pass.

Where is Mammoth Cave?

Mammoth Cave National Park’s over 50,000 acres are primarily located in Edmonson County, near the southern border of Kentucky. It’s about an hour south of Louisville and an hour and a half north of Nashville, TN.

The nearest towns are Park City (14 minutes away) and Cave City (18 minutes away) which is also the home of Dinosaur World, another popular destination with families.

Mammoth Cave is a great addition to any family road trip. Make sure you have the best road trip gear, easy road trip snacks, and the best ways to entertain kids on the road.

Exploring Mammoth Cave with Kids

To explore the caves, you must have a ticket for a guided tour. They strongly recommend purchasing tickets ahead of time as they can sell out weeks in advance.

There are lots of different tours to choose from at Mammoth, we’ve got a rundown of the best cave tours at Mammoth so you can pick the one that is right for your family. There are short and long walking tours, lantern tours, more adventurous tours that require you to crawl at times, and one that is fully wheelchair accessible.

The Extended Historic Tour

We choose the 2 1/2 hour Extended Historic Tour for our family. We were a little worried that it would be a lot of walking for our kids- then 4 and 7, but they both loved it-they had a great time and had no problem with the walking and climbing.

The tour begins at the Historic entrance, then descends a flight of stairs and through a wide opening.

As you continue into the cave, you’ll follow a comfortable path, before entering the impressive Rotunda. From here you can see the remnants of saltpeter mining that used to occur in the cave.

As you move through the dimly lit cave, you’ll pass such fascinating features as “Bottomless Pit” and “Giant’s Coffin”. Your guide will highlight areas as you walk, and tell stories about the history of the cave.

Toward the end of the tour the passages narrow, so that you may have to duck and turn sideways to pass through them. This area is nicknamed “Fat Man’s Misery”, and was one of the most fun parts for the kids.

At the end of the tour, you’ll climb a metal tower of steps to reach the exit. This area is where you have the most steps at any one time.
