Cal & RIoslyn are/were the owners of Glamis North, in Niland. Really nice folks. They may have taken on partners or sold....they were getting up there in age. Hense, the addition of Palm Spings RV Park to the name. Have not gone this year due to physical issues so can't confirm. The restaurant if I remember right hasn't been operating since the Cv19 closures plus Cal told us it's hard to keep a cook/chef employed locally that is only open for half a year.
Tons of rv camp spaces as well as a handful of park models.
You can tell it was a hip place back in its heyday but definitely shows it wear. They have 2 larger hot spring pools that they drain/refill after a few days and several large 2 person tubs you can fill from the hot spring. Also two larger pools they keep clorinated which is where the kids usually play. Riding trails are accessible "legally" with ohvs, both west towards the sea & bat caves created by San Andreas fault and eastward toward Chiriaco and/or Palo Verde, etc.
