Without the nation's massive man-made caverns, we wouldn't have access to natural deposits of Play-Doh, glow-in-the-dark Gak, and Michael Bolton records. Gaze at platinum-selling sedimentary strata with today's Groupon: for $6, you get a one-hour tour of the Louisville Mega Cavern, located near the Louisville Zoo on Taylor Avenue. Check Louisville Mega Cavern's website for seasonal availability.

Once a massive limestone quarry that has seen more than four decades of rock-blasting, the Louisville Mega Cavern contains 17 miles of corridors located about 100 feet below the ground. During the tour, which lasts about an hour (valued at $13.50 for adults, $8 for children ages three to 11, and $12 for seniors and military), you'll explore the subterranean abyss on a guided tramcar. Spot a replica of the Cold War–era civil defense fallout shelter, designed to protect upstanding citizens from Soviet Stay Puft Marshmallow Man attacks. Eye-feasters can spot exquisite rock formations under the light of strategically placed lamps, and with no walking on the tour, relax as they take in historical information on the cave's early mining operations. Few will experience claustrophobia within the cave's four million square feet of space, an area so immense that the Empire State Building could squeeze inside and have sufficient spire-room left in its sleeping bag.

Temperatures inside the Louisville Mega Cavern hover around a brisk but comfortable 58 degrees all year, so cold-blooded spelunkers should consider wearing a jacket or fur tuxedo. Step inside the earthen expanse and avoid the sky's oppressive solar disco ball with today's Groupon to Louisville Mega Cavern.

Louisville Mega Cavern

The newest attraction at Louisville Mega Cavern, Mega Underground Bike Park just opened in February 2015 in addition to Mega Quest, opened in Fall 2013 and claims to be the only underground ropes challenge course in the world. The Mega Cavern, originally a limestone mine, was mined for 42 years, beginning in the 1930s, and is now the largest building in the state of Kentucky. The cavernous facility utilizes its 90-foot-high thoroughfares to unite guests with an exhilaration previously known only to highly caffeinated miners—Mega Zips.......ziplining in a cavern. Customers can purchase separate tickets for a variety of attractions. Open daily throughout the year. The Lights Under Louisville show running during the Christmas season, the Mega Tram, which runs beginning in mid-January through early October. During Mega Zips tours of up to two hours, amateur spelunkers will stream across the subterranean's six underground ziplines and dual racing lines under the sage supervision of the cavern's ACCT-certified experts. Along the way, guides will entertain guests with tales of the cavern’s rich history and uncanny impressions of stalagmites.
