We stayed at 44.612620,-120.211000 - it seems like that's not the location posted here but I don't know if that's a good site as well so I won't edit the record.

We stayed here one night when we were visiting the Painted Hills. This is a great spot if you’re visiting the area. It’s easy to get to and plenty of room, and an easy drive to the Painted Hills. There were 4 of us camping here the night we stayed (3 other RVs and one van), and everyone cleared out in the morning. 

It’s not really a place I’d stay at for more than a night. There is a bunch of dumped garbage and an abandoned car at the end of the loop, but there were plenty of spots and room before you get to that spot. There's some rutted parts of the road when you get off the paved road, just watch for that, especially after rains.

The area is nice and quiet, you hear the creek and lots of birds. You’re near the road so you do hear cars but it wasn’t bothersome. You hear the creek but really you can’t get to it, it’s very marshy and overgrown and no real path to the water. Verizon had zero cell reception (weboost didn’t help) and ATT had one bar LTE. 

No amenities here, please pack out your trash and human and dog waste.
