Visitors traveling to Mammoth Cave National Park can camp, hike trails through the lush greenery, take cave tours, ride the rivers, or go horseback riding. With 52,830 acres to explore above and below ground, this national park provides endless adventures. The regional airports at Louisville, Kentucky and Nashville, Tennessee make it easily accessible for tourists.
