Grand Canyon Skywalk, Arizona
A cantilever bridge that allows people to walk way past the edge of the world's most famous canyon, the Grand Canyon Skywalk is popular among sightseers and thrill-seekers. Easily recognizable in photos because of its distinctive horseshoe shape, the glass floor allows visitors to look down at the base of the canyon, nearly 4,000 feet below. At its farthest point, the walkway is 70 feet beyond the edge of the cliff. The Skywalk in Grand Canyon West is on land owned by the Hualapai Tribe, which oversees its operation. The western section of the canyon is actually closer to Las Vegas than it is to the more well-known sections of the canyon to the east (including the popular South Rim area).
