Each year the Louisville Mega Cavern is transformed into an underground holiday light spectacular for the Christmas season. Load up the kids and enjoy a 30 minute ride through part of 17 miles of underground passageways, which features over 850 lit characters with over 2,000,000 points of light. It's the only underground light show of its kind on the planet!

Mega Cavern's Lights Under Louisville allows the public to drive their own vehicles inside the cavern, during the Christmas season, to experience this one of a kind holiday transformation. It's a great way to get your family in the mood this holiday season, so load up the kids and enjoy the sights and sounds of Lights Under Louisville.
