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.

We had a fantastic experience renting an RV from David at RV Easy. From start to finish, the process was smooth, professional, and stress-free. The delivery was right on time, and David took the time to thoroughly walk us through the trailer, explaining how everything worked and reviewing any pre-existing wear or damage. Throughout our trip, he was quick to respond to any questions we had and even came out promptly to help us with an issue we couldn't figure out ourselves. The pickup process was just as easy and hassle-free as the delivery. David was professional, knowledgeable, and clearly takes pride in providing excellent customer service. We felt completely confident both in his abilities and in the quality of the trailer we rented. I would highly recommend David to anyone considering an RV rental. We will definitely be renting from him again in the future!

david was a great host, very responsive with messages and flexible with pick up when our plans shifted. It was our first family camping trip with the kids and we had a wonderful weekend with the trailer. The kids loved the bunk beds!

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.
