Cannot beat the location of this RV Park and Marina.  If you are camping in your RV/Van the best spots are waterfront ones which are also the most expensive. But the expansive views are worth it and the marina is picturesque and proximity to all restaurants and all that downtown Port Townsend has to offer is very hard to beat. There were open spots in February but I bet this place is really hard to get in in the summer. Plan ahead!
