Dispersed camping is allowed in the nearby Kaibab National Forest. Some existing sites are present but you can pretty much pull off and camp anywhere (following Leave No Trace principles, of course). Cooler temperatures because of the elevation made this a fantastic place to camp.
site: some sites larger than others. geared towards RVs. amenities: less than great facilities. attractions: near North Rim I would go to the North Rim to camp.
