Grand Canyon Skywalk The #Grand Canyon is a steep-sided canyon carved by the Colorado River in the state of Arizona in the United States. It is contained within and managed by Grand Canyon National Park, the Hualapai Tribal Nation, the Havasupai Tribe and the Navajo Nation. The Skywalk, managed by the Hualapai Tribe and located on tribal lands, consists of a horseshoe shaped steel frame with glass floor and sides that projects about 70 feet (21 m) from the canyon rim. While the Skywalk is the most famous attraction at Grand Canyon West, tours also include other points of interest and unique canyon views.
