Mega Cavern: Explore Underground Louisville

Our first sighting of Mega Cavern came as a shock. We were expecting a huge tourist attraction, not a working cavern. We parked in the small parking lot and began our descent into the underground by wandering through a hall filled with fun facts about the history of the cavern. (Did you know the temperature of the cavern stays at a balmy 58 degrees year round?) We arrived at the underground activity center and waited for our tour to begin. Because one of the past functions of the cavern was a government fall -out shelter in case of nuclear attack during the Cuban Missile Crisis, we watched propaganda videos made by the government during our wait. It was a fascinating slice of history.

Tours begin on the hour and soon we were boarding the Mega Tram for our adventure through the underground. Our guide immediately made everyone feel at home by sharing a few jokes and a brief history of the cavern. The cavern was designed as a limestone quarry in the 1930โ€™s and is still in use as a business today. Boasting high security storage, the cavern is now used by government agencies and high security businesses such as Loomis, who were looking for a virtually indestructible storage facility. We passed business after business as our guide explained the cavern could withstand damage from earthquakes or manmade disasters.

A favorite stop for the kids on the tour was the recycling center. Our guide explained how paper was brought into the cavern and consumed by Canadian red worms to make an extremely fertile soil. When our guide asked if anyone would like to taste a worm, one brave soul raised his hand to prove to his nephew he did not mind eating a worm. While several kids offered to be test tasters, our guide assured us this opportunity was only available to people over 18. The kids were appropriately awed and never realized, due to the darkness, that the adult had been given a gummy worm.

I enjoyed the replica of the fall-out shelter, designed for 50,000 people in the 1950โ€™s. With only four highly secured entrances, the families who would have moved into the cavern planned to stay there until after the nuclear fallout was over and it was safe to return above ground.ย The tour lasted approximately 70 minutes and kept both the kids and adults entertained with tidbits of history, geology and even a few ghost stories for the brave of heart!

  • Zip Line Tours throughout the cavern are available for the brave and offer an up close look at the caverns which cannot be seen from the tram.
  • Tickets are $13.50 for adults and $8 for children 3-11. They can be purchased in advance.
