If you are going to the North Rim check if it will be open. It closes early as it is higher and has snow usually early. It's beautiful and not to be missed, if at all possible. It didn't open until the middle of June when we went and had closed early in the fall. Also need reservations most of the time as it fills up fast. We (2 motor-homes) were there the first day it opened at 8 am and we got the last two spots (without reservations). Have a great trip and look around as you go or you'll miss a lot of this beautiful country.
