Free dispersed camping, about 2 miles outside of Quartzsite, with no services available, but lots of space and beautiful views of surrounding mountains. Be sure to register with the Camp Host on duty near the entrance to the area. The major drawback is that you can hear the traffic on Interstate 10. Many RVers use solar panels for all or at least part of their power needs though, so generator use is minimal.
Sunrises and sunsets are endless and beautiful! Easy access back into town for food, gas, firewood, laundry, and just about anything an RVer or camper could need.
