If you’re planning holiday activities in the area, this is one to add to your list. The full drive-through takes you through over a mile of lights underground and it’s such a fun seasonal thing to do!! This years cavern experience has over 7 million lights with over 1,000 displays. This was my first time going and it did not disappoint🎄♥️ #louisvilleky #louisvillechristmas #megcaverns #lightsunderlouisville2025 #thingtodoinlouisville
