This cavern has 100 acres of fun and entertainment all underground and is said to be the safest place in Kentucky by geologists.
Founded by Ralph Rogers in the early 1930s to the early 1970s, the limestone quarry here had been mined and blasted for use in the building of roads and bridges for over 42 years. It is so big that it is referred to as a mega cavern with 100 acres of space inside and is always 58 degrees. Private investors acquired the cavern in 1989 because they wanted to develop part of it into a high-security commercial storage facility. Since the beginning of the 1990s, much has been done to work on floors and roads inside and to carve out offices and some storage spaces. It is the largest building in the state of Kentucky, and it has its own building code. The Mega Cavern is under 70% of the Louisville Zoo and under all 10 lanes of the Watterson Expressway (I-264).
Today, the Mega Cavern is mega entertainment and fun! They have a tram tour through the caverns, a bike park, 6 zip lines and 2 challenge bridges, Mega Quest with 76 challenging elements, and so much more. The Mega Tram tour takes 1 hour and 10 minutes and teaches about the history of the cavern, the mining techniques used, recycling of the limestone, and green building technology of this man-made cavern. During November and December, the cavern is changed into "Lights Under Louisville." Guests drive their own vehicles through a part of the cavern where 850 light displays and 2 million lights make the holidays special.
