James Island Marine State Park

James Island Marine State Park sits low on the horizon, small and unassuming next to its neighbors in the San Juan archipelago. This tiny marine state park, accessible only by boat, may be the ideal retreat.

Remote as it seems, James Island is not to be missed. Featuring emerald coves, forested trails, spectacular views and an isthmus with two white sand beaches, the park offers only 13 primitive campsites – three for travelers arriving by human- or wind-powered watercraft and 10 sites clustered in two groups on different sides of the isle. There is moorage available for those who prefer to sleep in the comfort of their vessels.

You’ve worked hard to get here. Now it is time to relax and experience the lightly touched beauty of this watery paradise.

Park features


James Island Marine State Park is a 113-acre marine camping and moorage park with 12,335 feet of saltwater shoreline on Rosario Strait. Much of James Island has been designated a Natural Forest Area and is closed to public access, except for designated recreational areas and 1.5 miles of high bluff trails with extraordinary views.
