Clark Island Marine State Park is located midway between Orcas and Lummi islands and encompasses the entire 55-acre island with 11,292 feet of saltwater shoreline on the Strait of Georgia. Beaches are sandy on the west side of the island and smooth pea gravel on the east side, making this one of the few San Juan Islands locations with extensive sandy shoreline. The island features forested interior areas and provides important habitat along the northern edge of the San Juan Archipelago.
This is a popular kayaking site that provides an important camping and rest site for paddlers traversing the northern San Juan islands. The park serves as a critical stopover for marine recreation enthusiasts, offering a peaceful retreat accessible only by watercraft with camping opportunities directly on the beach.
The park has 15 campsites, one composting toilet and two vault toilets. There are two picnic sites on the west side of the island with a sandy beach area. Fire pits and picnic tables are provided at campsites. Cell service is sporadically available here because Clark Island is close to a cell tower on Orcas Island. No garbage services on the island, practice Leave No Trace principles.
Camping is available on a first-come, first-served basis with 15 primitive campsites open year-round. Campsites 1-6, 14 and 15 can accommodate up to eight campers each. Campsites 7-13 can accommodate up to four campers each. Campsite 15 is suitable for small groups up to 12 persons and may be reserved by calling 360-376-2073. The nearest fuel and a limited selection of groceries are available at Blakely Island Marina.
Clark Island Marine State Park is accessible only by boat or kayak. The closest launch sites are at Obstruction Pass, Orcas Island; Washington Park, Anacortes; Cap Sante Marina, Anacortes; Squallicum Harbor, Bellingham. Boaters anchoring offshore or using the park moorage buoys should be aware of the strong currents on the west side of the island. East side moorage is subject to large waves created by commercial ships. This park has nine moorage buoys, six on the east side of the island and three on the west side. No vessels over 45 feet long are permitted on buoys. A Discover Pass is required for day use.
Clark Island Marine State Park offers an authentic island camping experience with rare sandy beaches and peaceful solitude, making it a premier destination for paddlers and boaters seeking a true San Juan Islands adventure.
Washington trails are wet more often than not, and the right gear makes the difference between a great day out and a miserable one. We recommend KEEN Targhee IV Waterproof Hiking Boots for solid traction on muddy and rocky terrain, a North Face Alta Vista Rain Jacket because you will need it even on days that start sunny, and the REI Co-op Flash 22 Pack to carry your layers, water, and snacks. All three are available in men's and women's versions. (affiliate links)
