Monument Valley Navajo Tribal Park more than lives up to indelible images popularized by the films of John Ford and others. Giant pinnacles of rock standing as high as 1,000 feet are surrounded by miles of mesas and buttes bathed in harmonious colors and the shadow play of clouds. Be certain to book a tour with a Navajo guide in order to see otherwise inaccessible or off-limits (people live here) areas. Stunning at any time of day, at sunrise or sunset it is extraordinary.
