Monument Valley is a Navajo Tribal Park located along the Arizona and Utah border and is famous for the massive sandstone formations that are icons of the west.
The most popular tour is the Self Guided Valley Drive. The road into the valley is dusty and rough, like the Navajo Reservation, but it is really like few other places, with the massive weather carved sandstone blocks. They remind you of how tiny we are. Many of the formations have names, the first along the route is Elephant Butte.
One stop where there is some walking is John Ford's Point. One of the features of Navajo parks is that there are vendors at every stopping point selling their artwork. They are somewhat overwhelming. The stands they sell from are usually slapdash and rickety but they do have a lot of turquoise and silver jewelry, pots, kachina dolls, and the fabulous Navajo rugs. There were a lot of foreign languages being spoken at the view points, and not all ones that I could recognize.
