Grand Canyon West Skywalk and Eagle Point, Peach Springs

Nearly a mile above the Colorado River in Grand Canyon West, the 10-foot-wide SkyWalk extends 70 feet beyond the canyon's rim. If its height weren't enough, its glass platform helps make a stroll around the horseshoe-shaped cantilever bridge one of the more audacious in the country—but not to worry, as the SkyWalk is strong enough to hold 70 fully loaded passenger jets.

Opened in 2007, this marvel of engineering boasts a spectacular vantage point of the canyon; in particular, a focal point of the view is Eagle Point, a naturally carved erosion of the canyon wall that resembles a massive eagle taking flight. In addition to the panoramic lookout, visitors are able to explore several dwellings of the region’s indigenous tribes—including the Hualapai, Navajo, Plains, Hopi, and Havasupai—in the Native American Village or enjoy a dance in the amphitheater.
