If you’ve lived in Bellingham for more than a week, you know the drill. The sky turns that specific shade of "Pacific Northwest Grey," the mist settles into your bones, and suddenly, the idea of an outdoor hike feels less like recreation and more like a soggy chore. This is exactly when the Arne Hanna Aquatic Center becomes the unofficial living room of the city. It’s not just a pool. Honestly, calling it a "pool" feels like a bit of an undersell. It’s a massive, multi-functional hub where retirees do their morning laps, toddlers have their first "oh-no-water-in-my-nose" moments, and teenagers try to look cool while failing spectacularly on the diving board.
Located right on Potter Street near the Civic Field complex, it’s basically the heartbeat of the city’s Parks and Recreation department. But here’s the thing most people miss: it’s actually a pretty complex operation. It isn't just about dumping some chlorine in a tank and hoping for the best.
What Actually Happens Inside the Arne Hanna Aquatic Center
Walking through those front doors, the first thing that hits you is that unmistakable smell of nostalgia and pool chemicals. It’s comforting, in a weird way. The facility is broken down into four distinct areas, and if you go at the wrong time for your specific vibe, you’re going to have a bad time.
The lap pool is the serious business zone. We’re talking eight lanes, 25 yards, and a temperature that stays around 81 to 83 degrees. If you’re a serious swimmer, this is your sanctuary. But don't expect a leisurely float here; there's a rhythm to the lap lanes that locals take very seriously. Then you have the instructional pool. This one is warmer—usually hovering near 88 degrees—which is a godsend for physical therapy or for kids who haven't built up that "Bellingham insulation" yet.
Then there’s the beach entry leisure pool. This is where the chaos lives. It has a water slide that's about 150 feet long, which sounds fun until you realize you have to climb all those stairs. It’s great. It’s loud. It’s exactly what a community pool should be.
The Hydrotherapy Factor
Hidden away is the hydrotherapy pool, or what most of us just call the "hot tub." It sits at a steady 102 degrees. People underestimate how much the city relies on this for rehabilitation. I’ve talked to folks who swear by it for managing chronic back pain during our damp winters. It’s 102 degrees of pure relief. But there’s a catch—it’s small. On a busy Saturday, you’re going to be shoulder-to-shoulder with a stranger talking about their knee surgery. That’s just the Bellingham way.

Why Everyone Gets the Schedule Wrong
The biggest gripe you’ll hear at a local coffee shop? "I went to Arne Hanna and it was closed for a swim meet."
Yeah, that happens. A lot.
The Arne Hanna Aquatic Center is the home turf for basically every high school swim team in the area. Bellingham High, Sehome, Squalicum—they all converge here. If you don't check the seasonal "Leisure Guide" or the online portal, you might show up ready for a soak only to find 40 teenagers doing butterfly sprints.
The city uses a software system for registration now. It’s better than the old days of just hoping for a spot, but it requires a bit of pre-planning. You can’t just roll up at 4:00 PM on a Tuesday and expect an open lane. You’ve gotta be tactical. Most regulars know that the early morning "Dawn Patrol" or the late-evening sessions are the sweet spots.
The Technical Reality: Keeping the Water Safe
People rarely think about the engineering behind a place like this. The Arne Hanna Aquatic Center uses a sophisticated filtration system to keep things sanitary. We’re talking about thousands of gallons of water being cycled constantly. They use a combination of chlorine and UV light systems. The UV part is actually pretty cool—it kills the stuff that chlorine struggles with, like Cryptosporidium.

If you’ve ever noticed that "pool smell" is particularly strong, that’s actually not the chlorine itself. It’s chloramines, which form when chlorine reacts with... well, human stuff (sweat, oils, etc.). The staff at Arne Hanna are pretty militant about the "shower before you enter" rule for this exact reason. If everyone showers, the water stays clearer and your eyes don't sting as much. Simple math.
Is it Actually Affordable?
Bellingham isn't exactly getting cheaper, but the aquatic center remains one of the few "bang for your buck" spots left. They have a sliding scale for low-income residents through the "PIRCH" program. It’s one of those things that makes you proud to live here. No one is really turned away because they can't afford a swim.
For the average person, a drop-in is a few bucks. But if you're going more than once a week, the 10-visit or 3-month passes are the only way to go. It pays for itself remarkably fast, especially if you use the sauna. Oh, did I mention there’s a sauna? It’s dry heat, it’s wood-lined, and it’s the best place to hide when the wind is whipping off Bellingham Bay at 40 miles per hour.
Programs You Didn't Know Existed
- Deep Water Aerobics: This isn't just for your grandma. It's a brutal workout. You wear a buoyancy belt and move against water resistance. It’s zero-impact but high-intensity.
- American Red Cross Training: They are a major hub for lifeguard certification. Half the kids working at summer camps in Whatcom County got their start in these lanes.
- Specialized Kayak Hours: Occasionally, they open it up for people to practice their rolls in a controlled environment. Try doing that at your local gym.
The "Arne Hanna" Legacy
Who was Arne Hanna? People ask this all the time. He wasn't some distant politician; he was a dedicated city employee, a parks director who actually cared about public spaces. He retired in the late 80s, and the center was named in his honor when it opened in 1995. It’s a legacy of service. That’s why the staff generally seems like they actually want to be there. They’re carrying on a tradition of community-first recreation.
How to Not Look Like a Tourist
If you want to blend in at the Arne Hanna Aquatic Center, there are a few unwritten rules.

First, the locker rooms. They’re functional, but they’re high-traffic. Don't be the person who takes up three benches with their gym bag. Space is at a premium.
Second, the lane etiquette. If you’re in a lap lane, you need to know if it’s "circle swimming" or "split lane." If there are more than two of you, you’re circling. Stay to the right. Don't stop in the middle of the lane to adjust your goggles. It’s like stopping your car in the middle of I-5; it's dangerous and everyone will be annoyed.
Finally, bring your own lock. They have lockers, but they don't provide the locks. You can buy them at the front desk, but you’ll pay a premium for the convenience. Just grab one from your garage before you head out.
Actionable Steps for Your First Visit
If you're ready to take the plunge, don't just wing it.
- Check the Current "Pool Schedule" PDF: The City of Bellingham updates this seasonally. Search for "Arne Hanna Pool Schedule" on the official COB.org site. Look specifically for "Open Swim" versus "Lap Swim" times.
- Create an ActiveNet Account: If you plan on taking a class or want to buy a pass, do this online beforehand. Doing it at the front desk while a line of shivering kids stands behind you is stressful for everyone.
- Pack the Essentials: Beyond the suit, bring a towel (they don't provide them), flip-flops for the locker room floors (trust me), and a water bottle. The air inside is humid and surprisingly dehydrating.
- Arrive 15 Minutes Early: Especially if it’s your first time. You’ll need to navigate the parking lot, which can be a nightmare during soccer season at Civic Field, and get your bearings inside the facility.
- Respect the Lifeguards: These folks are mostly students or young adults, but they are highly trained. If they tell you to stop running or get off the lane line, just do it. They’re there to make sure nobody drowns, which is a pretty important job.
The Arne Hanna Aquatic Center is a bit of a local treasure. It’s not fancy. It’s not a high-end spa with cucumber water. It’s a workhorse of a building that keeps Bellingham moving when the weather tries to shut us down. Whether you’re training for a triathlon or just trying to burn off some toddler energy on a Tuesday morning, it’s the place to be. Just remember to shower first.
