If you moved to Belfair, North Mason, or anywhere along the Hood Canal in the last year or two, someone has probably already told you: you can dig your own clams here. They weren’t exaggerating, and they probably undersold it. Shellfish harvesting is one of the most distinctly Pacific Northwest things you can do — and Hood Canal is one of the best places in Washington State to do it. Here’s how to actually make it happen in 2026, including what changed this spring that even longtime locals may not know.
Yes, You Can Actually Do This
Hood Canal is a deep fjord-like inlet that runs along the west side of the Kitsap Peninsula, and the North Mason stretch — from Belfair south through Union — sits right at the southern end. The warm, relatively shallow waters of Hood Canal create ideal conditions for Manila clams, native littlenecks, mussels, oysters, and yes, geoduck. The public beaches here are harvestable — legally, freely — by anyone with the right license and gear.
The best public shellfish beach in the immediate North Mason area is Potlatch State Park, about 12 miles north of Belfair on Hood Canal Highway (Highway 101 North). The beach at Potlatch has extensive oyster beds near the highway and solid Manila clam habitat across the tide flats. Season for clams, mussels, and oysters runs April 1 through May 31, so right now is actually a great window to go.
What You Need Before You Go
1. A shellfish license — required for anyone 15 or older. Buy online at fishhunt.dfw.wa.gov or at most sporting goods retailers (Walmart, Fred Meyer, local tackle shops). Cost is modest and covers the season. Without it, you’re subject to a citation on the beach.
2. A Discover Pass — required for parking at Potlatch, Belfair State Park, and most state trailheads. $30/year or $11.50/day. Get it at discoverypass.wa.gov or at licensing agents like Fred Meyer. If you’re going to use any state park or DNR land regularly — and in North Mason you will — the annual pass pays for itself fast.
3. Gear — a small clamming rake or hand shovel, a mesh bag or bucket, waterproof boots or old shoes. Nothing fancy. You’ll get better at reading the sand as you go.
4. A biotoxin check — this is the critical one. Marine biotoxins (primarily paralytic shellfish poisoning, or PSP) are a real hazard in Hood Canal. You cannot see, smell, or cook them out of shellfish. A beach that was fine last week may be closed this week due to an algae bloom. Check the Washington State DOH Shellfish Safety Map at doh.wa.gov/ShellfishSafety.htm or call 1-800-562-5632 before every single trip. This is non-negotiable, and it’s what separates people who’ve lived here for years from tourists who get sick.
The 2026 Rule Changes You Need to Know
Even if someone walked you through clamming last year, note that WDFW updated regulations effective April 1, 2026:
- Cockle minimum size is now 2½ inches (up from 1½ inches). Cockles are the round, ribbed clams you’ll find mixed in with other species. Measure before keeping.
- Geoduck daily limit is now 1 per person per day (down from 3). Geoduck are the giant clams with the iconic long siphon — you’ll know one when you see the “shows” (holes and dimples in wet sand at low tide). The limit cut is about protecting slow-recovering intertidal populations.
Understanding the Tides
Successful shellfish harvesting is entirely tied to the tide cycle. You want to be on the beach during low tide — ideally a minus tide (below 0 feet on the tide chart), which exposes areas that are normally underwater. The NOAA tide prediction for Hood Canal (the Bangor or Union reference station works well) gives you the exact window. A good rule of thumb: arrive about 1–2 hours before the predicted low tide and leave as it comes back in.
What Else Is Happening Outdoors Near Belfair Right Now
While you’re getting oriented to the outdoor recreation picture in North Mason, a few other updates for spring 2026:
Tahuya State Forest — Just west of Belfair, Tahuya is a sprawling DNR trail system used for mountain biking, hiking, and OHV riding. Portions of the Howell Lake Loop Trail are currently closed due to a washed-out bridge. The rest of the system is open — check current conditions at dnr.wa.gov/GreenMountainTahuya before you go.
Mary E. Theler Wetlands — One of the best free outdoor experiences in Belfair is right in town. The Theler Wetlands (600 NE Roessel Rd) has miles of trails through estuary habitat. This summer, crews from the Hood Canal Salmon Enhancement Group will be building a new 1,200-foot elevated boardwalk to reconnect the full loop trail across the restored estuary. The preserve is still open during construction — just expect some activity in the area.
Belfair State Park — The Tree Loop campground opens for reservations May 15 at washington.goingtocamp.com. Sixty sites, tents and small rigs, right on Hood Canal. It’s your local swimming beach, kayak launch, and evening campfire spot for the summer. Book early — it fills up.
Frequently Asked Questions
Where is the best place to dig clams near Belfair, Washington?
Potlatch State Park, about 12 miles north of Belfair on Hood Canal Highway, is the closest and best public shellfish beach. Manila clams, native littlenecks, oysters, and mussels are all available during the spring season (April 1–May 31). Always check biotoxin status first at doh.wa.gov/ShellfishSafety.htm.
Do I need a license to dig clams on Hood Canal?
Yes. A Washington State shellfish/seaweed license is required for anyone 15 or older. It costs around $12–15 for a fishing/shellfish combination license and is available at fishhunt.dfw.wa.gov or local retailers including Fred Meyer and Walmart.
What are the new shellfish rules for Hood Canal in 2026?
Two key WDFW rule changes took effect April 1, 2026: cockle minimum size increased to 2½ inches (from 1½”), and geoduck daily limit dropped to 1 per person per day (from 3). All other standard limits for clams, mussels, and oysters remain in effect.
What is a biotoxin and why does it matter for Hood Canal shellfish?
Marine biotoxins, including paralytic shellfish poisoning (PSP) from harmful algae blooms, can accumulate in shellfish and cause serious illness. They can’t be detected visually or by cooking. Hood Canal has a history of PSP closures. Always check the DOH status map at doh.wa.gov/ShellfishSafety.htm or call 1-800-562-5632 before harvesting.
What is the Theler Wetlands and can I visit it this summer?
The Mary E. Theler Wetlands is a 135-acre nature preserve in downtown Belfair at 600 NE Roessel Rd, managed by the Hood Canal Salmon Enhancement Group. It’s free and open to the public with several miles of trails. This summer, crews will be building a new elevated boardwalk to reconnect the estuary trail loop — expect construction activity but the preserve remains accessible.
