Driving the 17-mile self-guided loop lets you see most of the major scenic attractions of Monument Valley Navajo Tribal Park at your own pace, and at the lowest cost. The dirt road is a bit rough -- not recommended for low-slung sports cars or vehicles longer than 24 feet, although it is passable for smaller motor homes. The road's first half-mile is the worst, and you have to drive it both at the beginning and end of the loop. There are no restrooms, drinking water, or other facilities along the route, and motorists should watch for livestock. Allow about 2 hours.

A free brochure and a more detailed booklet ($1) provide rough maps and information on 11 numbered sites, such as the Mittens -- rock formations that resemble (you guessed it) a pair of mittens -- and the aptly named Elephant and Camel Buttes, Totem Pole, and the Thumb. You'll also see Yei-Bi-Chei, a rock formation that resembles a Navajo holy man, and John Ford Point, one of famed Hollywood director John Ford's favorite filming locations, where he shot scenes from Stagecoach, The Searchers, and Cheyenne Autumn. It's still popular with producers -- watch for crews working on feature films, TV shows, or commercials.
