If you’ve ever looked at a map of Washington and followed the coastline north until you practically hit the Canadian border, you’ve probably seen a little crescent-shaped bite taken out of the land. That's Birch Bay. It’s one of those places that people in Whatcom County try to keep quiet about, but then they go and host a massive Polar Bear Plunge that makes international news, so the secret is kind of out.
Honestly, Birch Bay is weird in the best way. It doesn't feel like the rugged, "I might get swept out to sea" vibe of the Olympic Peninsula. It feels like a throwback. Like a summer camp from the 70s that never quite grew up, but recently got a multi-million dollar facelift.
The Berm: It’s Not Just a Pile of Rocks
For years, the main road through town was basically a sacrificial lamb for winter storms. One big king tide and the pavement was toast. Then came the Birch Bay Drive and Pedestrian Facility Project, which everyone just calls "The Berm."
You’ve got to understand how much this changed things. They moved 105,000 cubic yards of sand and gravel to recreate the natural shoreline. It’s a 1.6-mile stretch that basically saved the town from falling into the sea, but for us, it just means there’s a killer limestone path for walking, biking, or just leaning against a bench to watch the sunset over the Gulf Islands.
The coolest part? It actually works. During a massive storm in January 2021, while other coastal towns were drowning in debris, the berm just sat there and did its job.
Why the Water is Weirdly Warm
If you jump into the Puget Sound in Seattle, your heart might stop. It’s freezing. But Birch Bay is famous for having some of the warmest saltwater north of California.

Wait. Don't go thinking it’s the Caribbean.
It’s warm because the bay is incredibly shallow. When the tide goes out—and it goes out way out—the sun bakes the sand and mud all day. When the water rushes back in over that hot ground, it picks up the heat. On a good July day, it’s actually pleasant to swim in. You'll see kids splashing around 200 yards from the shore and the water is still only up to their knees.
Tidepooling Without the Cliffside Drama
Low tide is basically the main event here. When the water retreats, it reveals a massive playground of tide pools. You don't have to scale a cliff to find them. Just walk out.
You’ll find:
- Giant green anemones tucked into the rocks.
- Dungeness crabs scuttling through the eelgrass (check the regs before you grab one, though).
- Sand dollars—thousands of them.
- Great Blue Herons standing perfectly still, looking like they're judging your choice of footwear.
Speaking of footwear: Wear rubber boots. Or at least some old sneakers you don't mind getting muddy. The "beach" is a mix of sand, cobble, and crushed shells. It’s not a Florida white-sand situation. It’s rugged, it’s messy, and it smells like salt and life.

Where to Actually Eat (The Local Hits)
Birch Bay isn't a "fine dining with white tablecloths" kind of place. It’s a "fries in a paper basket" kind of place.
- The C Shop: This is non-negotiable. It’s been around since 1971 and it's seasonal (summers only). They make their own candy and the smell of the cinnamon rolls will literally pull you off the street. It feels like stepping into a Hallmark movie, but without the cheesy dialogue.
- Bay Breeze Restaurant & Bar: If you want the view, go here. It’s right on the water. Their fish and chips are legit, and they have a rooftop patio that is the best spot in town for a sunset drink.
- The Beach at Birch Bay: They call themselves the "World's Only Five-Star Dive Bar." It’s loud, it’s fun, and it’s the soul of the community.
- Beach Cat Brewing: A newer addition but a great one. It’s dog-friendly and has a killer view of the bay. "Right Meow" is their catchphrase. You get the vibe.
Birch Bay Washington USA: The Big Events
If you show up on the Fourth of July, be prepared for chaos. It’s one of the few places where the fireworks show is basically a "bring your own" free-for-all on the beach. It is loud, smoky, and absolutely legendary.
Then there’s the Polar Bear Plunge. Every January 1st, thousands of people—and I do mean thousands—run into the freezing water at noon. On January 1, 2026, the community actually went for a Guinness World Record to beat the previous mark of 3,134 participants. Whether they hit the number or not, the sheer energy of 3,000 people screaming in the North Pacific is something you don't forget.
The State Park Factor
At the south end of the bay lies Birch Bay State Park. It’s 194 acres of forest and beach.
Most people just stick to the shoreline, but you should hit the Terrell Marsh Interpretive Trail. It’s a half-mile loop through a rare saltwater estuary. It’s quiet, it’s spooky in the morning mist, and it’s where you’ll see the best birdlife. There are 167 campsites there, but good luck getting one in August if you didn't book six months ago.

What Most People Get Wrong
A lot of people think Birch Bay is just a stopover on the way to Canada. It’s not. It’s a destination in its own right, especially if you’re into the slower pace of life.
There are no malls. No high-rises. No real "rush hour" unless you count the line for ice cream at The C Shop.
The biggest misconception is that it's only a summer town. Sure, it’s quiet in November, but there’s something hauntingly beautiful about the bay when the fog rolls in and you’re the only person walking on the berm. The winter "First Day Hikes" led by park rangers are a great way to see the wildlife—like the snowy owls that occasionally visit or the massive rafts of scoters on the water.
Making the Most of Your Visit
If you're planning a trip, don't just wing it. The tides dictate everything here.
- Check the Tide Tables: A "minus tide" is what you want for the best beachcombing. If you show up at high tide, the beach is basically gone.
- Get a Discover Pass: You’ll need it to park at the State Park. You can buy them at the automated pay stations in the park.
- Bring Binoculars: Between the eagles, the herons, and the occasional whale sighting out toward the islands, you'll regret leaving them at home.
- Respect the Harvest: If you’re planning on digging for clams, you need a license and you must check the Department of Health’s shellfish safety map. Paralytic Shellfish Poisoning is no joke.
Basically, Birch Bay is for people who want to breathe. It’s for people who want to see the sky turn purple over the Salish Sea and don't mind getting a little sand in their shoes.
Next Steps for Your Trip:
Check the current Washington Department of Fish and Wildlife (WDFW) schedule to see if crabbing or clamming seasons are open during your visit, and book your campsite at the State Park via the Washington State Parks reservation portal at least four months in advance for summer weekends.
