If you just moved to North Mason County, you may have driven past the brown sign for Belfair State Park without realizing what it actually offers. Here’s the short version: a 65-acre state park sits at the southern end of Hood Canal’s Great Bend, with 3,720 feet of saltwater shoreline, a restored estuary, ADA-accessible day-use facilities, and a campsite reserved exclusively for paddlers as part of a National Recreation Trail that stretches all the way to the San Juan Islands.
Most new residents take a year or two to discover this. Treat this article as a shortcut.
What the Cascadia Marine Trail Actually Is
The Cascadia Marine Trail (CMT) is a National Recreation Trail managed by the Washington Water Trails Association in partnership with Washington State Parks. It strings together more than 55 shoreline campsites along the inland marine waters of Washington — Puget Sound, Hood Canal, the Strait of Juan de Fuca, the San Juans — and it is reserved for human-powered and wind-powered watercraft. Kayaks. Canoes. Stand-up paddleboards. Sailing dinghies that can be muscled to a beach.
You cannot drive to a CMT site. That is the whole point. The trail exists to give paddlers a multi-day route through Washington’s marine waters with low-cost, designated places to camp along the way. Belfair State Park’s CMT campsite — site 148 — is the trail’s southernmost stop on Hood Canal. From here, paddlers head north up the canal toward Twanoh, Potlatch, and Hoodsport, then connect to the broader trail.
What the State Park Offers Day-Trippers
You don’t have to be a paddler to use the park. The day-use side has:
- 3,720 feet of saltwater shoreline along the southern Hood Canal Great Bend
- A historic tidal swimming pool that warms up in summer
- Picnic areas, ADA-accessible restrooms, coin-operated showers
- Trails through restored saltmarsh between Big Mission Creek and Little Mission Creek
- A drive-in campground (separate from the paddler-only CMT site)
You need a Washington Discover Pass for vehicle parking — $10 day or $30 annual. If you live in Mason County and plan to visit any of the state’s parks more than three times a year, the annual pass pays for itself by your fourth visit.
The History You’ll See on the Shoreline
One of the things that makes Belfair State Park genuinely interesting — versus just scenic — is that you can read its history on the ground.
Between 1952 and 1960, the original tidal marsh was graded, filled, and channelized to make room for parking, a swimming hole, and a more conventional state-park experience. Both Mission Creeks were straightened. A tidal gate was built. About 67,000 cubic yards of fill went in. Saltmarsh function was largely lost.
Starting in the 2010s, Washington State Parks and the Hood Canal Salmon Enhancement Group began undoing the damage. According to project records published by the Pacific Northwest Salmon Center, the project has restored approximately 8.1 acres of estuarine wetlands and removed 2,700 feet of rip-rap shoreline armoring. Walking the shoreline today, you can see tidal channels reforming, reed grass spreading into the shallows, and the creeks meandering closer to their original courses. It’s an active, visible piece of restoration ecology — the kind of thing you can show visiting family and explain in two minutes.
Long before any of that, this stretch of shoreline was a Skokomish gathering and harvesting place. The cultural history is older than the park, older than the state. Worth carrying with you when you visit.
Your First Three Visits, in Order
If you’re new to North Mason and want to actually use this park rather than just drive past it, here’s a starting sequence:
- Day-use afternoon. Pack a picnic, walk the saltmarsh trails, watch the tide, leave by sunset.
- Borrowed-kayak morning. If a friend has a kayak — or you can rent from North Shore Hood Canal Kayaks at 3959 NE North Shore Road in Belfair (call ahead, no walk-ins) — paddle the protected water near the saltmarsh on a calm morning.
- Pair it with Tahuya Forest. Spend a Saturday split between the park in the morning and Tahuya State Forest in the afternoon. That’s two of North Mason’s signature outdoor places in one day.
Frequently Asked Questions
Is Belfair State Park free?
Day-use parking requires a Washington Discover Pass — $10 per day or $30 per year, per vehicle. Camping fees are charged separately at the park’s self-registration. The $12 Cascadia Marine Trail site is paddler-only and cannot be reached by car.
Where exactly is Belfair State Park?
The park is on NE Beck Road in Belfair, just off SR-300, at the southern end of Hood Canal’s Great Bend in Mason County, Washington. From the SR-3 / SR-300 junction in downtown Belfair, it’s a short drive west along the canal.
Can I camp at Belfair State Park without a kayak?
Yes — the park has a separate drive-in campground for car campers. The Cascadia Marine Trail campsite (site 148) is reserved exclusively for paddlers and wind-powered watercraft and cannot be accessed by vehicle.
What is Hood Canal’s Great Bend?
The Great Bend is the sharp curve where Hood Canal turns east before its long northern reach. Belfair State Park sits at the southern end of this curve. The geometry of the bend creates protected paddling water and gives the area a distinct fjord-like character.
Are there restaurants near Belfair State Park?
Downtown Belfair is a short drive away and offers a range of casual restaurants, coffee shops, and a Saturday market. For waterfront dining, restaurants along North Shore Road and SR-106 east of the park provide additional options. Plan ahead for weekend evenings — seating fills.
Can I see salmon at Belfair State Park?
The estuary restoration is rebuilding juvenile salmon habitat in Big and Little Mission Creeks. Best viewing is from the boardwalk and shoreline trails during outgoing tides in summer and fall. Adult salmon return to nearby Hood Canal streams; the park itself is primarily juvenile-rearing habitat.
