Underground Wonders: 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.

The 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. With so much to see and do, a visit to Mammoth Cave with kids is the perfect destination for a family vacation.

We visited Mammoth Cave on our Epic Cross-Country Road Trip as part of our Family Year Out when our kids were 4 and 7.

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.

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.

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, 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, which is down 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.

Mammoth Cave National Park is a wonderful place for watching the night sky. With night programs for all ages, or tips for the individual stargazer, getting away from the city and out into nature is a great way to see the stars without all the light pollution.

Yes. Mammoth Cave is kid-friendly and most of the tours are great for kids of all ages. You can choose your tour based on time, distance, and amount of steps.

We chose the Extended Historic Tour which lasts 2 1/4 hours, covers 2 miles, and has 540 steps. Our kids were 4 and 7 when we visited and they both loved it and had no issues.

There are some areas where you will have to duck and watch your head and there is a place called Fat Man’s Misery which gets quite narrow.

The cave’s Mammoth Dome is 192 feet high and the Bottomless Pit is 105 feet deep.
The name of the cave refers to its large width and length of passage just inside the entrance that connects to the Rotunda. No fossils of woolly mammoths have ever been found in Mammoth Cave.
Two of the more interesting animals that live in Mammoth Cave are the eyeless cavefish and crayfish, both of which have fully adapted to a life without daylight.
Frontiersmen quickly realized that Mammoth Cave contained saltpeter (used in making gunpowder), and during the War of 1812, Hyman Gratz and Charles Wilkens established a commercial saltpeter leaching factory there.
From 5,000 years ago until nearly 2,000 years ago, Native Americans also explored and mined the upper three levels of Mammoth Cave. Covering over sixteen miles of the system, they sought gypsum, selenite, mirabilite, epsomite, and other related minerals.
