We drove to Mazama campground only to be told and they had just filled their last spot but that there was free overnight parking 18 minutes in each direction either by thousand springs snopark or Annie’s. We chose thousand springs. We were originally a bit underwhelmed by the large asphalt parking lot as we were hoping for something a bit more cozy with more nature. While stretching our legs we noticed that there was a dirt road up into the forest with a few slits as well. There was a perfect spot for our van. It was private and there was beautiful scenery all around us. I don’t think there would not be room for an RV. We were the only van there. There is a pit toilet closer to the gravel lot. Note that free overnight parking without a sno-park parking permit is only permitted between May 1 and November 14.
Next to the road so there is a bit of noise, but there are not too many cars that drive by at night. Be aware that there is a lot of wildlife in the area. There is no cell service. I would avoid this spot after heavy rain as some vehicles may sink into the dirt.
