May 11, 2023, Historic Entrance of Mammoth Cave

Gigantic cave. A number of historical traces, from graffiti to saltpetre mining in the cave, but few stalactites. If you want to see stalactites, you should rather visit the Carlsbad Caverns.

The Historic Entrance of Mammoth Caves has been open to the surface for thousands of years, and there is evidence of prehistoric people using this opening for shelter and to gather resources. The area is free to the public, and extends roughly 300 feet into the cave. You will need to descend around 65 stairs in order to access the cave. The area can be very popular in the summer, so there may be a wait in order to enter the cave.
