Louisville Mega Cavern

This Is the Most Unique Holiday Lights Show in the U.S.

"Beneath the streets of Louisville, this former limestone mine—used from the 1930s through the ’70s and now the largest human-made cave system in North America—spans about 100 acres and four million square feet, reimagined today as an underground playground. The cavern holds steady at 58 degrees year-round and its natural arches and soaring stone ceilings turn tunnels into dramatic passageways that amplify spectacles like Lights Under Louisville; because it’s fully dark all the time, visitors don’t have to wait for night to enjoy light displays. It’s easily accessible just off I-264, less than 10 miles from downtown, with plenty of free on-site parking." - Karthika Gupta Karthika Gupta Karthika Gupta is an avid outdoor enthusiast and enjoys writing about brands and products in the outdoor, lifestyle, beauty, and travel space.
