Do make a stop an Monument Valley. It is beautiful, awe inspiring, just magnificent. Gouldings RV is the only game in town. Really a nice full hookup RV park, fantastic view, lots of dust. The road there is an easy drive, two lane with no traffic. We went by way of Mexican Hat Rock. Gouldings has fuel, small town stores, and a rather good restaurant at the top. Don't miss John Wayne's cabin used for several movie shoots, up by the office and restaurant. Monument Valley is well worth a days stop. You can take one of the many tours with Indian guides, booked at the RV office, or if you have a high clearance toad you can drive it yourself, there is still a fee. We drove a Saturn Vue. The rutted dirt path through Monument Valley reservation area is best travelled very slowly, like 5 to 10 mph as it is potted, rutted, and covered with boulders. Still, we loved it. Happy Trails.
