Harstine Island park with 10 standard and 2 partial-hookup vehicle campsites, showers, forest trails, and protected saltwater moorage.
Jarrell Cove State Park is reached by road across the Harstine Island bridge or by boat. The current park page lists 10 standard vehicle campsites, two partial-hookup sites, and one Cascadia Marine Trail site reserved for travelers arriving by wind- or human-powered watercraft. Standard sites 5, 6, and 7 and the marine site are first-come; the other campsites are generally reservable year-round. Restrooms and showers are available. The pumpout serves boats at the cove; the park does not list a trailer dump for RVs.
Jarrell Cove State Park occupies a quiet forested cove on Harstine Island in southern Puget Sound, where the island's undeveloped interior and protected marine shoreline preserve habitat typical of the Sound's once-widespread island ecosystems. The surrounding Case Inlet and Pickering Passage waters provide important habitat for harbor seals, river otters, and the Dungeness crab harvest that has sustained tribal and commercial fishing in southern Puget Sound for generations. Harstine Island's low development intensity makes Jarrell Cove one of the quietest and most ecologically intact state park settings remaining in Puget Sound, with osprey nesting in tall snags visible from the moorage float throughout summer.
Practical guidance assembled from current operator maps, park pages, and clearly identified community observations.
This small park has an intimate cove setting — every site feels close to the water. Sites 1–10 nearest the cove shoreline are the nicest. Moorage buoys in the cove make this a favourite with boaters; expect boat traffic from morning. Very quiet on weeknights — one of the least crowded good parks in Puget Sound. The forested loop trail around the cove is a pleasant evening stroll from camp.
