This is Army Corps of Engineers recreation site with dispersed camping, vault toilets and a boat ramp. First come first served, $0 and you can stay up to seven days. I have a view of Mount Hood and am parked facing the river.
The downside? Very close to the railroad tracks and there are a lot of trains, mostly during the day. There is also a lot of truck traffic during the day. It doesn’t bother me, but your mileage may vary.￼
