Twanoh State Park sits along the southern reach of Hood Canal, and the campground managed by Washington State Parks splits its character across Highway 106. The wooded sites on one side back up against a creek and a trailhead; the beach, group areas, and docks are a short road-crossing away. Reservations are available, and they matter here: summer crowds are a consistent theme in reviews, with sites described as close together and largely open to neighboring campers. Off-season visits change the equation considerably. Saraj B. noted in April that "I only saw two other couples the entire day," with just the sound of the canal and creek for company.
Site quality varies more than a quick scan of the listing suggests. Some spots are spacious and face the creek directly; others sit exposed to highway noise with little vegetation buffer. Campers in the hiker-biker sites, located on the highway side, report more wind and traffic sound than those in the standard wooded sites. RV users should note the 35-foot length limit is real: at least one reviewer with a 35-foot fifth wheel found trees too close to fully extend both a slide and an awning on site T36. Solar panels may also struggle given the tree canopy on the wooded side.
The Hood Canal access draws most visitors. Oyster picking along the beach, SUP use, swimming, and dock jumping all come up repeatedly in reviews. The forested trail starting at the campground is short but well-used and stays muddy enough in wet months to warrant waterproof footwear. Fishing and crabbing are listed activities, though at least one reviewer found the crabbing unproductive, noting catches were too small to keep.
Full hookups with electric, water, and sewer connections are available for RVs up to 35 feet, alongside showers, a dump station, and WiFi. The campground runs year-round, with nightly rates from $12 to $51. A convenience store sits a few miles west. Campers exploring campgrounds around Twanoh will find additional options nearby, including Hike In Primitive Sites — Twanoh State Park and Riverside Camping a couple of miles to the northwest.
Come in spring or fall for elbow room, or book early if summer is the only option.
Description
The park has the feel of an old-time camping resort but with modern amenities. It's known for its warm saltwater swimming, scenic beauty, and abundant shellfish.
Kayakers and paddlers share space with seals, and boaters motor out in search of the perfect crabbing or fishing spot. At low tide, oyster shuckers emerge, carrying pails and hand tools. Fishing or shellfish harvesting licenses are required to take part in those activities.
Washington Discover Pass is required for parking which is sold on-site.
