Mammoth Cave CAVES, LAKES & CORVETTES Corvette FAST CARS & IMPRESSIVE CAVES 154 Kentucky has a big, beautiful world underground, and we’re not afraid to show it o – whether by a virtual simulation of a mini cave collapse at the Corvette Cave-In exhibit’s Skydome Sinkhole Experience or a wild adventure involving free-climbing and crawling through passageways at the real thing: Mammoth Cave National Park . From Lost River Cave (we found it!) and Hidden River Cave (we reveal it!) to the intriguingly named Outlaw Cave and the blinged-out Onyx Cave, there is much to explore below ground in Kentucky. Above ground, too, at Kentucky Down Under Adventure Zoo and Dinosaur World . Come closer. That’s right. Peer 30 feet down a manhole to see the fl oor of a sinkhole – a natural disaster that helped created one of the most exciting exhibits of all at the National Corvette Museum . THERE'S MUCH TO EXPLORE BELOW AND ABOVE GROUND. 1-800-225-8747 / 1-800-225-TRIP
