Twanoh State Park sits on the south shore of Hood Canal, combining 192 acres of coastal forest with nearly 3,200 feet of warm saltwater beach. The 62-site campground draws families for swimming, shellfishing, and short forest hikes. Sites are small and closely spaced, but the beach access and clean facilities keep visitors coming back.
Twanoh features a developed, family‑oriented campground set in forest next to a marine day‑use area and beach. The park supports both RV and tent camping with nearby day‑use picnic shelters and boating access.
Weather and SeasonsSummer offers the warmest, sunniest weather and the best beach experience at Twanoh. Daytime highs typically range from the mid-60s to upper-70s°F with water temps often in the mid-50s to low-60s°F, making swimming, boating, and tidepooling most pleasant. All park facilities and boat launch are usually operating, so fishing, family beach days, and longer evening campfires are at their peak. Expect higher weekend crowds and book campsites well in advance to secure a shoreline site. Spring and fall bring mist-kissed mornings and quieter trails when the summer rush clears out.
Natural Features and SceneryThe park straddles two worlds: a moss-draped forest canopy above the campsites and a broad pebble-and-sand beach at the water's edge. A creek runs through the campground, providing white noise for sites along its banks. Hood Canal's tidal flats expose shellfish beds at low tide, and the relatively shallow water warms faster than most Puget Sound beaches. A 1.7-mile loop trail winds through old-growth and second-growth forest behind the campsites. Highway 106 runs close to the campground, bringing occasional road noise to sites near the entrance.
