We visited Zion, Bryce and N. Rim on this trip. With all the driving, you would think the scenery would be redundant at times. All 3 parks were so awesome in their own ways. And this particular drive so different from any other place. Engineering of the road aside, the scenery was "so different." I still can't figure out how checkerboard was formed. And for those of you with young boys, didn't you feel like you're driving through the set of "Cars?"
Traffic does get heavy, allow time.
