There are several RV parks in this general area, just off the Columbia River parkway. The other two we visited were the kind where the sheriff/police cars slowly drive through to make sure things aren't getting too crazy. This is not that kind of place.
Smaller (25 spots?) and about half the spots are long-term residents. Lots of grass and trees. Laundromat and showers. Nothing too fancy but also nothing too sketchy.
Good location as far as a jumping off point for the Columbia River Gorge while being not too far from Portland proper.
