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

The cavern spans under a number of roadways above and is part of 17 miles of corridors located under the Louisville Zoo. 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 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:

• 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. 

A light sweater or jacket is recommended.

Photography is welcome.

Because you ride through the cavern and never walk, it is especially convenient for parents with small children, seniors and physically challenged. 

A wheelchair tram is available for those needing additional assistance, please call ahead to reserve the handicap tram.  Click here to contact us.  Handicap parking is also available inside the main entrance to the Louisville Mega Cavern.  You must have a valid handicap parking permit. 

 Now everyone can experience the natural beauty of the Louisville MEGA Cavern!
