A nice little (120 spaces or so) full hookup (30 and 50 amp) campground.  We paid $289 for 5 nights. Clean, well maintained and full of families.  Very close to downtown and Anza-Borrego Visitor Center.  Spaces are good size, no problems fitting our 30' toy hauler towed by F250, and the park is well laid out and easy to drive. Checkin was fast and easy.  There are full time residents, but they are in a different section.  We used it as a base for hiking and off-roading at Octotillo Wells (both recommended,but bring as much water as you  can carry). The property has an old west theme, and there is also a hotel , laundromat and restaurant. If you have never visited this part of California, be advised that the wind here can be VERY intense, especially at night.  Also note that Borrego Springs is a dark sky community, so please be respectful and remember to look up and enjoy the stars.
