We're about a four-hour drive from the Grand Canyon. In just over a week, we'll drive around the end of it en route to Utah to visit my In-Laws. A couple of years ago, we took our pop-up trailer for the annual visit to Utah, and stayed a night at the North Rim of the Canyon on the way back.
We keep considering taking a week or more and doing a Northern Arizona/Southern Utah National Park camping trip. Just a short drive north of the Canyon is Zion National Park, which also has some breathtaking scenery. Bryce Canyon is a little more up the road. The Petrified Forest National Park, which also includes the Painted Desert, is a couple of hours east of the Canyon here in Arizona.
Here's a photo of our P'up in the campground at the North Rim.
