Atop the Skywalk, you stand 4,000 feet above the Grand Canyon on a horseshoe shaped walkway with a glass floor that projects 70 feet from the canyon rim. Dramatic canyon vistas spread out on either side of you, as well as below. Look down and you feel as if you are “hovering” atop the canyon. The Skywalk is situated on the Hualapai (WALL-uh-pie), Reservation at the western end of the canyon, about 250 miles — five hours by car– from the South Rim and 60 miles northwest of Peach Springs, Ariz., the tribal headquarters. An on-site cafe sells snacks and sandwiches. Park at the Grand Canyon West Airport Terminal and take a shuttle to the site.
