Next stop in a June cross-country National Park trip is Grand Canyon. Our family will be driving from Bryce and plan to spend the afternoon at the Best Friends Animal Sanctuary. We will be camping 2 nights at the North Rim. Wondering if there are any other stops we should do on the way to GCNP? Also, we will have one full day to spend in the park. Wondering what highlights we should not miss? Is there anything close in the area that is a must see/do? We plan to leave the following day for Zion. Any suggestions would be greatly appreciated!
