Things to do at Clark Island Marine State Park
- Boat-in Camping Moderate
Clark Island has 15 campsites, 9 buoys for moorage, 2 picnic areas, a sandy beach, and opportunities for clamming, crabbing, and fishing. Sites are primitive and first-come, first-served, so plan arrival early on summer weekends. nps.gov/places/clark-island-marine-state-park.htm
- Sea Kayaking the San Juans Strenuous
Clark Island is a classic destination along the Cascadia Marine Trail for experienced paddlers crossing from Orcas or Lummi. Strong tidal currents and ship traffic demand trip planning, VHF radio, and immersion gear.
- Beachcombing and Picnicking Easy
The island has a sandy beach and 2 picnic areas that make it an easy day stop for boaters. Sheltered coves on the east and west sides give options depending on wind direction.
- Clamming, Crabbing, and Fishing Easy
Clark Island offers opportunities for clamming, crabbing, and fishing along its shoreline. Visitors must carry a current Washington shellfish or fishing license and check seasonal closures before harvesting. nps.gov/places/clark-island-marine-state-park.htm
- Wildlife Watching Easy
The waters around Clark Island are part of the Salish Sea and host seals, porpoises, bald eagles, and occasional orcas. Bring binoculars and keep the required distance from marine mammals.
- Day Trip from Orcas Island ModerateRV parking available
Many RV travelers base at an Orcas Island campground and launch small boats or charter from the east side of Orcas to reach Clark. This keeps the RV on paved roads and ferries while still allowing a full island experience.
- Exploring Nearby Marine State Parks Moderate
Sucia Island Marine State Park is widely considered the crown jewel of Washington's marine state parks, with 814 acres and ten miles of hiking trails accessible only by watercraft, plus two docks and 48 buoys for anchorage. Pairing Clark with Sucia, Matia, or Patos makes for a strong multi-day San Juans itinerary.

How to get to Clark Island Marine State Park
RV travelers cannot drive to Clark Island; access is by private boat, kayak, or charter. Common staging points include Bellingham (about 20 miles southeast by water) and the Washington State Ferries terminal at Anacortes, roughly 80 miles north of Seattle by road, with onward ferry service to Orcas Island where small-boat launches sit closest to Clark. Drivers towing trailers on I-5 and SR-20 should plan for the Deception Pass Bridge height and narrow shoulders, and verify Washington State Ferries vehicle length limits before booking. The nearest commercial airport for fly-and-rent trips is Bellingham International Airport, with Seattle-Tacoma International as a larger alternative.
