Beautiful but small FCFS campground. Do your research on which Black Canyon Park campground you’d prefer before starting your drive, as the east and north campgrounds are at least an hour and 45 minutes apart.
The North Rim campground was pretty and quiet. I arrived right at 1 to make sure I could get a spot the Friday of Father’s Day weekend. By 5:30, all the spots were full and were full earlier the following night, so be sure to arrive early. Cool drinking water access was a nice surprise, and there are bear boxes for each site as well as two clean vault toilets and a dumpster. There is (limited) WiFi at the ranger station but zero service anywhere in the park or campground, so plan ahead.
The campground is down a long dirt road, it was well maintained but be prepared to be in a remote location.
