Some mention

crowded

"Reviewers consistently praise Jones Island for its exceptional scenery, quiet marine setting, well-maintained trails and composting toilets, excellent sunsets from west- and south-facing sites, and friendly habituated deer. It is a favorite for kayakers and boat-campers but can get crowded in summer and has limited moorage."

Jones Island Marine State Park

48.6176, -123.0483

Accessible only by private boat or human- and wind-powered craft; there is no road or car access to the island.

Best Time to Camp at Jones Island Marine State Park

Plan your visit between mid-May and mid-September when drinking water is available on-island, though self-sufficient boaters are welcome year-round (just pack your own water supply in the off-season). The San Juans' maritime climate means layers are your friend—even summer days can bring cool breezes and misty mornings that give way to brilliant sunshine. For a quieter experience, consider visiting on weekdays or shoulder season; summer weekends see the moorage and campsites fill quickly with fellow island-hoppers seeking this special slice of Pacific Northwest paradise.

Planning Tips

About Jones Island Marine State Park

Escape to your own island adventure at Jones Island Marine State Park, a secluded gem nestled in the heart of the San Juan Islands. Accessible only by boat, this forested sanctuary offers primitive waterfront camping where you'll fall asleep to lapping waves and wake to breathtaking sunsets over the Salish Sea.

Primarily primitive tent and boat-access campsites, including designated Cascadia Marine Trail (human-powered) sites; no developed RV or cabin lodging.

Natural Features and SceneryWander through enchanting groves of towering Douglas-fir and fragrant cedar, their branches draped in emerald moss, before emerging onto sun-drenched bluffs crowned with twisted madrone trees. The island's 25,000 feet of rocky shoreline invite exploration—follow the scenic loop trail as it winds through the forest and hugs the western shore, revealing hidden pocket beaches, dramatic cliff viewpoints, and front-row seats to nature's daily show. Watch harbor seals bob in quiet coves, scan for porpoises cutting through the waves, and observe seabirds diving for their dinner while colorful intertidal creatures cling to tide pools at your feet.
