Sucia Island State Park
October 2026
About
Among the northernmost of the San Juan Islands, Sucia Island is accessible only by watercraft. Boaters venturing into its coves and harbors quickly discover why Sucia Island is considered the crown jewel in the state marine park system and a boating destination that’s world class. The park is 564 acres with 77,700 feet of shoreline and abundant camping and moorage. The main island and several smaller islands comprise the "Sucia group." There are no services on this island, and fossil collecting is strictly prohibited in this and all Washington state parks.
Is Sucia Island State Park fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
