About Mammoth Cave in Kentucky

Mammoth Cave in Kentucky is the main attraction of Mammoth Cave National Park which was established in 1941 and became a World Heritage Site in 1981. Although these events took place in the 20th century, the cave has been in use for thousands of years. Leading anthropologists estimate that Native Americans discovered the cave as long as 4000 years ago.

Mammoth Cave National Park preserves not only the cave system but also parts of the Green River valley and the beautiful rolling hills of south central Kentucky. So even though it’s what’s beneath the surface that’s the main attraction, there are also miles of fine trails in the area ready to be explored when visiting Mammoth Cave.

In the cave you find bats that enjoy the darkness it offers. In other parts of Mammoth National Park you have the chance to spot black bears, white-tailed deer and a wide range of birds that call Kentucky their home.

The mystery of the Kentucky giant

When the first human entered Mammoth Cave about 4000 years ago, this person led way to a new world with discoveries of until then unknown minerals. From that time humans would make use of the cave for around 2000 years.

But, for some reason the cave turned quiet again. The people left and it remained quiet until the end of the 18th century. Then the curiosity of the European settlers unfolded the history of the huge Mammoth Cave.

To this day it remains a mystery why Mammoth Cave was left empty for roughly 2000 years. However, the same curiosity that brought the first human into Mammoth Cave is the same thing that keeps us coming back to the cave.

What to expect when visiting Mammoth Cave National Park

A visit to Mammoth Cave is a true showing of what the underworld is like. It’s damp, quiet and dark. And as it’s the Mammoth Cave it’s also huge!

The size of the cave and the atmosphere down under the surface of earth is enough to ground the most hard flirted person when visiting Mammoth Cave National Park. The cave has over 400 miles (640 km) of explored passageways, of which some are enormous and some are tiny.

All parts of the cave system have not yet been explored. In fact, it’s very likely that the system is much longer than 400 miles as all the unexplored passageways aren’t included in that number.

As big as Mammoth Cave is, as dark it also gets if you don’t keep your lights on. It happens that the guides turn the lights off in the middle of a tour to let you experience some real darkness as you visit Mammoth Cave.

Life in the cave doesn’t care much about what happens on the outside. The cave keeps a constant temperature of 54°F (12°) year-round. That makes visiting Mammoth Cave National Park a great year-round activity.
