Obstruction Pass Beach sits at Obstruction Pass State Park near Olga on Orcas Island in San Juan County, forming the largest public beach on Orcas Island within the 76-acre state park. The beach and pass take their name from the narrow waterway between Orcas Island and Obstruction Island to the southeast, creating navigational obstruction for vessels traveling through the San Juan Islands archipelago. The state park features quiet open forest, secluded walk-in campgrounds with 10 first-come first-serve sites, and 1.8 miles of hiking trails providing access to the beach through madrone forest and along bluffs with water views. The beach offers one of the few extensive public shoreline access points on Orcas Island where most waterfront remains in private ownership, making the state park particularly valuable for visitors seeking beach recreation and camping opportunities.
Hiking to the beach follows a 1.5-mile loop trail generally considered easy route taking average 41 minutes to complete, meandering down half-mile through low forest, up to bluffs with water views, and back down to the beach with two steep uphill sections followed by level forest path and short downhill stretch. The beach is covered with interestingly shaped rocks including distinctive triangular stones creating unique beachcombing opportunities, with smooth pebbles, driftwood, shells, and beach glass deposited by tidal currents flowing through Obstruction Pass. Swimming in the protected waters attracts hardy visitors during warm summer days though Puget Sound temperatures remain cool year-round, with the beach's southeastern exposure providing afternoon sun. Wildlife watching includes bald eagles soaring overhead and perching in shoreline trees, harbor seals occasionally visible in pass waters, great blue herons stalking tideline areas, and diverse seabirds utilizing the productive marine ecosystem where strong tidal currents create nutrient-rich feeding zones. Views capture Lopez Island visible to the south, Blakely Island to the southwest, Obstruction Island directly across the narrow pass to the southeast, and splendid water panoramas across the San Juan Islands archipelago. Kayaking and paddleboarding launch from the beach for exploration of Obstruction Pass though strong tidal currents require experienced paddlers comfortable with challenging conditions, with routes exploring nearby islands and protected coves. Camping at the 10 walk-in sites provides overnight access to the beach with sunset and sunrise viewing opportunities, though no potable water is available requiring visitors to pack in all water needs and pack out all waste. A Discover Pass is required for parking at the trailhead.
