Watch: 'Magical' Christmas lights shine deep in Louisville's Mega Cavern

Sure, many of us put up Christmas lights atop our trees and roofs, but what about underground? 

In Kentucky, Christmas magic is already on display in the form of a sparkling light show deep within a 100-acre cavern.

Dig deeper:

The "Lights Under Louisville" Christmas display shines in footage taken by Michelle Smith during a visit to the Mega Cavern earlier this month.

Visitors can drive through the display, which features over 7 million points of light spread through the cavern’s expanses.

What they're saying:

Smith told Storyful that her family goes to the show every year: "We all love it and look forward to going."

"Every year they make it bigger and better than the previous year," she added. "There’s something magical about driving in a cave full of lights, animations, and Christmas music."

What is the Louisville Mega Cavern?

Local perspective:

The Mega Cavern is a former limestone mine in Louisville, Kentucky, that has been converted into a tourist attraction featuring tram tours, zip lines, rope courses, and more.

The 4,000,000-square-foot site, about 75 to 100 feet underground, also houses other businesses and storage facilities.
