An underground adventure rich in history, geology, mining, recycling, green building technology, and just simply HUGE in scale!

The man-made cavern spans under a number of roadways above and is part of 17 miles of corridors located beneath the city of Louisville, Kentucky. It’s a great tour for all ages—whether you want to learn about science and history or simply want to see what a giant man-made cavern of this magnitude looks like!

You’ll hop on an SUV-pulled tram and be joined by a MEGA Cavern expert who will guide you on your underground adventure. It’s a 60-70 minute tour, strategically lit to enjoy highlights such as:

• Some Early Cavern Formations;


• A Historic Replica of the Cuban Missile Fallout Bunker;


• A Worm Recycling/Tasting Room;


• Sights and Facts of the Early Mining Operation;


• Hear About our Storm Dog and Pigeon Eating Hawk;


• And More Surprises Wait Around Every Corner!

Louisville MEGA Cavern is an all-weather attraction. The temperature inside the cavern hovers at a comfortable 58 degrees year round.

Because you ride through the cavern and never walk, it is especially convenient seniors and physically challenged.
