Hood Canal is not a canal. It is a 65-mile-long natural fjord, gouged out of the Olympic Peninsula by the same glacial advance that shaped the rest of Puget Sound roughly 13,000 years ago. The mistaken name dates from George Vancouver’s 1792 survey; he named the body for Admiral Samuel Hood and used the term canal in its older sense, meaning a narrow channel of water — not the dredged variety. The mistake stuck.
What lies behind the misnamed entrance is one of the most underused cruising bodies in the Salish Sea. Hood Canal sees a fraction of the boat traffic of Puget Sound proper or the San Juans an afternoon’s sail away. The water is the warmest in the region in summer — up to 70°F at the southern end in August, the warmest summer surface temperature in any PNW saltwater body. The Olympic Mountains rise directly from the western shore, snow-capped much of the year. And the oyster beds along the public tidelands produce some of the finest Pacific oysters in the world.
This is the working guide.
Getting in
The standard approach from Seattle is north through Admiralty Inlet, west around the north end of the Kitsap Peninsula, and south into Hood Canal under the Hood Canal Floating Bridge. The bridge is a real navigational feature: 1.5 miles of concrete pontoon spanning the narrowest section of the canal, fixed clearance of about 28 feet at high water. Most cruising powerboats and many sailboats with masts under 28 feet pass under the bridge without intervention. Larger sailboats request a draw — call the bridge operator on VHF 13 or 360-779-3233; the bridge accepts requests on a published schedule and accommodates boats that have called ahead.
The bridge is the longest floating bridge over a tidal waterway in the world. The structure is genuinely odd — the pontoon segments float and flex with the tide; the road moves with the water. Worth the spectacle on its own.
What Hood Canal is like
Hood Canal is calm. Reliably calm. Protected from the southwest by the Olympic Range and from the north by the Kitsap highlands, the canal sees far fewer whitecap days than the Sound proper. For powerboaters and small sailboats, this is a feature. For sailors hoping for a robust afternoon breeze, it is sometimes a limitation — Hood Canal can run dead calm when Shilshole is doing 15 knots.
The water is also notably clear. Visibility of 30+ feet is common in summer; divers come from across the region for the Hood Canal sea life — wolf eel, octopus, lingcod, the painted greenling that makes the Pacific Northwest a serious cold-water diving destination.
The mountains are the visual constant. Westbound from anywhere in the canal, the Olympic Range fills the horizon. The peaks rise from sea level to 7,000+ feet inside ten miles of horizontal distance — one of the steepest sea-to-summit gradients in the lower 48 states. On a clear morning the contrast between dark green water and snowfield and grey rock face is unforgettable.
Oysters, prawns, and what comes off the bottom
Hood Canal is synonymous with shellfish. The cold, oxygen-rich, glacially-fed water produces some of the finest Pacific oysters and spot prawns in the world.
Pacific oysters. Washington state designates specific tidelands as open for public recreational harvest. Bag limits are real and enforced; closures for paralytic shellfish poisoning (PSP) are common in summer. Check the Washington Department of Fish and Wildlife (WDFW) shellfish safety map before harvesting any shellfish — closures change daily based on biotoxin testing. Bring a bucket, a glove, and a proper oyster knife. Shuck on the boat or take whole oysters home.
Spot prawn season. WDFW opens a brief Hood Canal spot prawn season annually — typically a few days in May and June, exact dates published in spring. Prawn traps are dropped at 100–250 feet, baited with cat food cans punctured for scent. A spot-prawn dinner from your own boat, anchored in a Hood Canal cove with the Olympics turning pink at sunset, is one of the better PNW cruising experiences available. Check current regulations; gear restrictions, soak times, and bag limits are all enforced.
Dungeness crab. Available but regulated. Check WDFW for open areas and seasons; Puget Sound crabbing has been restricted in recent years to protect populations.
Licences. Both shellfish and crab require a current Washington State recreational fishing licence with the appropriate endorsements. Buy online before departing or at most marine chandleries.
The named anchorages
Pleasant Harbor State Park. A small, beautiful park near the northern entrance to Hood Canal. Mooring buoys and anchorage. Quiet, well-protected, and perpetually a favourite of experienced canal cruisers. Worth a layover.
Potlatch State Park. Mid-canal, on the Kitsap side. Mooring buoys and anchorage. Good access to public shellfish tidelands. Named for the traditional potlatch ceremonies of the Skokomish people, whose ancestral territory includes the canal.
Hoodsport. The main services town on Hood Canal. Hoodsport Marina has fuel, transient moorage, and basic provisions. The Hoodsport Winery (yes, a winery on Hood Canal — it has been there since 1978) is a short walk from the marina.
Twanoh State Park. Near the Great Bend at the south end of the canal. Anchor in 15–25 feet over good mud. Twanoh has the warmest summer surface water in the PNW — up to 70°F in late August. Swimming off the boat at this anchorage is genuinely pleasant, which is not a normal sentence about Pacific Northwest saltwater.
Belfair State Park. At the very head of the canal. Shallow and tidal — a different feel from the rest of the canal. Excellent birding. Approach carefully on a rising tide; the inner bay is shoal.
Tides and currents
Hood Canal has a pronounced tidal range — 12–14 feet on a spring tide. The main body of the canal carries moderate currents (1–2 knots peak); the narrows near the Great Bend and the upper reaches toward Belfair can run 3 knots. None of these is dramatic by PNW standards (Deception Pass at 8 knots is dramatic; Hood Canal at 3 is not), but timing matters for docking and for upper-canal navigation.
The Hood Canal Floating Bridge is easiest to pass at or near slack water when currents beneath the structure are negligible. Outside slack, the current runs perpendicular to the boat’s track and tries to set the boat sideways through the gap. Manageable, but more comfortable at slack.
Wildlife
Bald eagles are ubiquitous year-round. Multiple eagles every day is normal. They hunt the surface for the same fish that feed the salmon runs, and their presence is one of the constants of Hood Canal cruising.
Harbour seals at most anchorages. River otters near the northern reaches, less common but present. Great blue herons stalking the shallows at every stop. Roosevelt elk descending the Olympic Peninsula slopes to the canal at dawn and dusk — the lucky cruiser at anchor in Twanoh or Potlatch sees an elk on the beach before breakfast on a still morning.
Practical notes
Cell service is intermittent in the southern canal. Download charts and tide data before departure.
Fuel. Hoodsport Marina is the main fuel stop. Pleasant Harbor and Belfair have limited fuel availability. Plan accordingly — the canal is sparser in services than Puget Sound proper.
Weather. The Olympic Mountains create orographic effects on the western shore. Rain can come quickly and intensely from the west; the Olympic Peninsula’s western foothills receive more rainfall than almost anywhere in the contiguous United States. Carry foul-weather gear even in summer.
Recommended duration. Three to four days for a round trip with time to explore. Seven days for the full length of the canal — Pleasant Harbor north end, Twanoh south, oysters and prawns in season, layover at Hoodsport for fuel and a winery visit, Belfair on the head.
Closing notes
Hood Canal is what Puget Sound was forty years ago: less developed, less crowded, less obvious. The cruisers who go up the canal regularly tend to go up every summer, and they are not the cruisers who post about it on social media. Hood Canal rewards the visit; it does not demand attention.
The oysters at Twanoh are still on the rocks at low tide where they have been since the glacier retreated. The prawns at 200 feet are still there at slack water. The eagles are still in the trees, and the Olympics are still doing what they have done since the same glacier left them above the water.
