What It Is

A roughly 100-acre underground facility that was originally used from the 1930s to the early 1970s to mine limestone.  It has since been converted into a privately-owned “building” (the largest in the state of Kentucky) offering environmentally-conscious, high-security, commercial storage and family-friendly attractions, including a tram ride, a zip line, and an aerial ropes challenge course.

When We Went

July 2019

What We Did

We took a one-hour ATV-pulled tram ride through this man-made cavern.

How Much We Spent

We don’t have records of what this cost us in 2019.  However, as of September 2025, tickets cost $19.99 per person for everyone ages 3 and older.

How Much Time We Spent There

Each tour lasts 60-70 minutes.  We arrived about 15 minutes early, as instructed, but there wasn’t much to do or look at while we waited.  We left right after our tour was over.

What We Liked

The cavern was huge.  If it weren’t for the guided tram ride, it would be easy to get confused and lost.  We were all amazed that so much “land” was underground.

What We Didn't Like

We may be spoiled by other attractions we’ve seen, but Mega Cavern, in general, was a little underwhelming. The hallway we walked down, when we first arrived, had the feel of an old government building, and the inside of the facility, at least where we went for our tram ride, felt a little old.


Was it worth it? 

Honestly, it was a nice time, but I’m not sure we’d recommend it.  We weren’t overly wowed.  We largely went as a time filler.​

Did You Know?  The average temperature in the Mega Cavern is 58 degrees year-round.  However, one of the cavern’s four entrances experienced an 8-inch snowfall one day when the moist air escaping from the cavern hit the below-freezing temperatures outside.  It did not snow anywhere else in the city that day.​
