Although Deception Pass is the name of a strait in the San Juan Islands, the name is more commonly used to refer to Deception Pass State Park, the most-visited state park in Washington. The park has 134 partial hookup sites plus a dump station, and a few RV sites are big enough to accommodate vehicles up to 60 feet in length.State park RV campsites can be reserved up to nine months in advance of your stay, and they can book up quickly, especially if you're trying to get a reservation on a summer weekend. Fortunately, there are tons of alternative options in the area, from privately run RV parks to quiet, tucked-away spots that private landowners in the area rent out to campers and RVers on Hipcamp. Many are situated on private farms and some come with perks such as restrooms, shared kitchens or cooking areas, and fire pits.
