Kings Canyon National Park isn’t as busy as it’s neighboring National Parks, which makes it extra enjoyable. Our favorite campground was Sunset. It’s located near the third largest tree in the world and it also has cell service!
The North Rim Campground inside Grand Canyon National Park is a no-hookups campground with designated spots. If you don’t mind dirt roads, consider dispersed camping right on the rim on Forest Road 611 in Kaibab National Forest (pictured above).
