Louisville Mega Cavern

Explore Louisville Mega Cavern in a historic tram where you ride through 17 miles (27 km) of dark passageways beneath the city of Louisville. Learn about geology, history, mining techniques, recycling and green business technology as well as witness where 50,000 people would have sheltered during the Cold War Era. You can also go on 'Mega Zips', an adventure tour that features five underground zip-lines, three challenge bridges and over two hours of adrenaline. Another great tour only offered from November through December is 'Lights Under Louisville'. This underground holiday light show is perfect for the season, where guests drive through an underground passageway festooned with holiday lights.
