Are you craving a day at the beach on your San Juan island vacation?
Head out to Clark Island for your choice of fine-grained sand or warm gray pebbles.
Midway between Orcas and Lummi islands, this long stretch of land is the perfect napping, camping or relaxation spot after a big day of boating or paddling.
First-come, first-served campsites sit on the east side’s pea gravel strand. A short walk to the island’s west side leads to a sandy beach bookended by large rocks.
Sunsets here are spectacular, even on partly cloudy evenings, and watching the sunrise from your tent on the beach cannot be beat.
Once you’ve had a restorative visit, whether for an afternoon or a night, you’ll be reinvigorated and ready to sail or paddle forward on your San Juan island adventure.
Accessible only by boat, Clark Island Marine State Park is a 55-acre marine camping and moorage park with 11,292 feet of saltwater shoreline on the Strait of Georgia.
Boaters anchoring offshore or using the park moorage buoys should be aware of the strong currents on the west side of the island. The east side moorage area is subject to large waves created by passing commercial shipping in Rosario Strait.
Bug repellent is recommended into September, particularly for those using the more shaded camp spots.
Cellular phone service is often available here, as Clark Island is close to a cell tower on Orcas.
There are two picnic sites on the west side of the island with a sandy beach area.

Clark Island was first charted by Spanish explorer Francisco de Eliza in 1791. In Eliza’s map, Clark Island and neighboring Barnes Island were named Islas de Aguays after the Viceroy of Mexico.
The present name was established by Charles Wilkes during the United States Exploring Expedition of 1841. Commander Wilkes, an American explorer and naval officer, named the island for midshipman John Clark, who was killed in Perry's Battle of Lake Erie.
Clark Island was briefly homesteaded beginning in the late 1800s before being set aside by the federal government as a lighthouse reservation in 1932. The island was acquired by the Washington State Parks and Recreation Commission in 1964 from the Bureau of Land Management.
