I've heard that the price of Navajo tour is very expensive. I'm thinkin to go inside Monument Valley by my car.
Going with a Navajo guide added a lot, in our opinion. Made it more than just a drive-by. He told us the Navajo names for various formations, what significance they had, legends and lore, etc. It's a way for them to make money and after all, they were here first! about 4 years ago
