Discovered in the late 1890s by cowboy Jim White, Carlsbad Caverns is located near the Guadalupe Mountains of southeastern New Mexico and boasts the third largest cave chamber in the Americas. The park features a vast array of rooms and chambers: the Big Room, the New Mexico Room, King's Palace, Queen's Chamber, the Spirit World and more than 100 others. It was officially established as a national park in 1930, and since then, it has welcomed 400,000 visitors a year.
