Mammoth Cave National Park, Kentucky
Crawl Through the World’s Longest Cave
Mammoth Cave National Park, in central Kentucky, is home to the world’s longest-known cave—a 412-mile labyrinth of limestone caverns and passageways. Start at the Frozen Niagara entrance to check out a massive waterfall-like formation, 130 feet below the surface. For a more extreme caving expedition, sign up for the five-mile, ranger-led Wild Cave tour, which requires some gnarly belly-crawling and ledge-walking and takes about six hours to complete. For a self-guided adventure, try Laurel Cave, in Carter Caves State Resort Park, a couple of hours east of Mammoth.
