About as close-in Portland as you can get for an RV (not trailer) park, this place is on the North side of town right next to the river (with Vancouver, Washington not too far away). Not really much to do in this area or in the park iteself, but if you're passing through Portland and need a place to stay you could do much worse.

Basically a big, well organized parking lot with a few trees on the edge. Decently well maintained and even some bright flowers in planters. There's definitely some long-timers but not too run down and there's a separate area right at the entrance for more daily turn-over type spots.
