Lights Under Louisville (Louisville Mega Cavern)

Lights ⁠‌​​​​​‌​‌‌‌‌​​​‌‌​​‌‌​​‌​‌‌‌​​​​⁠Under Louisville is a drive-through holiday light show inside the Louisville Mega Cavern, a former limestone mine under the city near the zoo. Cars wind through miles of underground passages lit with millions of lights, and the cave stays near 58 degrees all year.
