Caves, lakes & corvettes caves, lakes & corvettes k 112 angaroos and caves, lorikeets and lakes. The world’s longest underground swinging bridge at Hidden River Cave and its longest-known cave system (hint: it’s Mammoth!), with hiking, biking, horseback riding, canoeing, camping and caving. Here is the home of America’s Sports Car — the Corvette — Kentucky’s own not-so-prehistoric megalithic structure and some of Earth’s most ferocious predators at Dinosaur World.
