Located on the border between Utah and Arizona. The valley is well-known for having been used in many films - most famously with John Wayne. Many films have been made here - too many to mention, so I suggest looking here: en.wikipedia.org/wiki/List_of_appearances_of_Monument_Val...
This is Navajo Nation country.
It's possible to tour many parts of the valley in your car or on a tour with a guide or even on horseback. I've done it in an "ordinary" car and although it's rough and sandy in places it's not too difficult.
