About this spot

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.
