About
Jarrell Cove State Park is a 67-acre marine camping park with 3,500 feet of saltwater shoreline in the northwest of Harstine Island enclosed by Puget Sound and surrounded by Case Inlet and Pickering Passage. The park is a watery haven with excellent opportunities for swimming, diving and boating. An amphitheater, sports fields and camping make for entertainment and activities on terra-firma.
Is Jarrell Cove State Park fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
