The Grand Canyon.Arizona.
Vast, magnificent and inarguably beautiful, the Grand Canyon is easily Arizona’s most distinguishable landmark – and a natural wonder that you simply have to see to believe. Stretching 277 miles from end to end, steep, rocky walls descend more than a mile to the canyon’s floor, where the wild Colorado River traces a swift course southwest.
