Sucia Island State Park is 2.5 miles north of Orcas Island, San Juan County and is accessible only by boat. The park features an underwater scuba park, over 6 miles of hiking trails, primitive camping, picnicking, clamming and crabbing. Sucia Island State Park was acquired in five parcels; the first in 1952 and the last in 1974, for a total cost of $6,818.67. The island's name originated with the Spanish Captain Eliza on his map of 1791. He named it "Isla Sucia". Sucia in Spanish means "dirty" or in a nautical sense "foul". This word was chosen because the shore was deemed unclean and reefy.
