Considering a trip to the North Rim of Grand Canyon. Afterwards taking in Monument Valley and the East Entrance to the South Rim. What's the best route (scenic but not too mountainous) from North ...
US 89A is the best route. From North Rim east, the highway drops down a fairly long grade. It doesn't really matter which way you go there is down hill grades. That means they are uphill toward the North Rim. Once you get down, it is fairly flat.
