Review:

One of the largest caverns in the US is found in Louisville, Kentucky. The cavern was created by a mining company to create a limestone quarry and was blasted in for over four decades before coming under private ownership in 1989.

Construction in the Louisville Mega Cavern is ongoing, with storage spaces and offices being built inside part of the four million square foot cavern. Although the cavern is underground, it is considered the largest building in Kentucky.

The Mega Cavern also has a tram and several attractions, including zip lines. The Mega Quest is also inside the cavern and features a series of aerial rope challenges all underground.

Visit during the holiday season to enjoy Lights Under Louisville, an underground Christmas lights display that stretches several miles.
