The campgrounds at Fort Worden, of which there are two, are operated and maintained by Washington State Parks. Reservations however are handled by the Port Townsend Public Development Authority (PDA) and they charge a one-time camping reservation fee. Fort Worden, in its entirety, is a state park and it is within the city limits of Port Townsend. Camping fees are more expensive ($35-$45) in the "primetime" season, May through September, and are cheaper in the "shoulder" season of October-April ($30-$40). Also, camping fees vary depending on whether the campsite is premium, basic, or economy. The lower beach campground is the most popular and there is a mixture of pull-thrus and back-ins and all sites offer FULL hook-ups with 30/20 amp service ( 4 sites with 50/20 amp only). The campsites are quite wide and the views of Admiralty Inlet, the Strait of Juan de Fuca, and Point Wilson lighthouse are fantastic. The upper campground is in a forest setting, sites are much closer together than the beach, and all sites offer 30/20 amp electrical and water. No sewer, but there is a dump station. And, there are no views of the water.
In April, be prepared for unpredictable weather. Normally, it can be very windy and rainy. The upper campground offers a little more protection from the wind.
Point Hudson RV Park, at the end of Water Street in Port Townsend, has some great views and is convenient to restaurants and the downtown area. It too can be quite windy as it sits out on the "Point". Depending on your site, you should be careful when deploying your slide lest you hit your neighbors slide and it does take some forethought when positioning your RV.
The SKP park in Chimicum, as someone mentioned, is very nice. For $40 annual membership, full hook-up sites are normally available for around $22/nite. Plus there are SKP parks located in various locations in the country.
Regardless of where you camp, have fun, be safe.
