The sites of Monument Valley are just unbelievable! The open air truck was the best way to travel the rough, unpaved terrain, not to mention, enabled us to have access to some roads that you wouldn't have been able to access otherwise. One tip to pass along is to make sure to go to the Welcome Center and not accidentally go to the Visitor Center like I did.........we were fortunate to catch up with the truck, but it was my fault for not reading my email more closely to see Welcome Center (i.e. there's a lot of signs pointing you to Visitor's Center, but very few (or at least I didn't see them in case they were there) for directing you Welcome Center. Our tour guide was so knowledgeable and had so many interesting stories and insights about the area, the history, the culture, etc.!!! Highly recommend!
