There's something about swimming outdoors that a chlorinated indoor lane can never quite replicate. The open sky overhead, the sun on your shoulders between sets, the sound of the world going on around you instead of an echoing tile ceiling. It turns a workout into an experience. And this Fourth of July, there's no better place in Seattle to feel that than Colman Pool.
In honor of the holiday, we're taking a look at why outdoor swimming hits differently, and why one of West Seattle's best-kept secrets deserves a spot on your summer list.
Here's a fun piece of trivia for your holiday weekend: Colman Pool actually opened on July 4, 1941. That makes this Independence Day its birthday, which feels fitting for a pool that's become a genuine piece of Seattle history. Tucked into Lincoln Park on the West Seattle shoreline, it's the city's oldest public pool, and it's the only saltwater pool in Seattle, filled with water pulled straight from Puget Sound and gently heated for swimmers.
There's something special about swimming in water that came from the Sound just hours earlier, rather than a treated tank. It's a different kind of swim, and a different kind of summer memory.
Ask any swimmer who's trained both indoors and outdoors, and they'll tell you the same thing: outdoor swimming just feels better. A few reasons why.
Open water teaches you to swim with awareness, not just rhythm. Indoor pools train you to count laps off a black line and a wall. Outdoor pools, especially ones with a view like Colman, invite you to actually feel your stroke instead of mechanically repeating it. That shift in mindset is part of what makes outdoor swimming feel more like play and less like a workout, even when you're putting in real effort.
Fresh air changes your whole relationship with breathing. There's a different rhythm to breathing outside, with real air instead of pool deck humidity bouncing off four walls. Swimmers often report that open-air pools feel easier to breathe in, which makes longer sets more enjoyable and less of a grind.
The scenery turns recovery time into a reward. Floating on your back between sets and looking up at an open sky, mountains, or in Colman's case, ferries crossing Puget Sound, makes rest intervals feel like a bonus instead of a pause. That mental reset matters more than swimmers usually give it credit for.
Saltwater has its own appeal. A saltwater pool like Colman gives you a bit of natural buoyancy you don't get in a standard chlorinated pool, along with skin and hair that don't carry that telltale chlorine smell home with you. For a lot of swimmers, it's simply a more pleasant medium to spend a few hours in.
Colman Pool isn't just historic, it's genuinely one of the most scenic places to swim in the entire city. The pool sits right on the shoreline of Lincoln Park, with Puget Sound, the Olympic Mountains, and passing ferries all visible from the water. It's a 50-meter, 8-lane Olympic-sized pool, which means there's room for everyone, from a serious lap swimmer working on technique to a family looking for a fun, relaxed afternoon.
A few things to know before you go. Colman is open seasonally, summer only, so this is exactly the time of year to take advantage of it. There's no parking directly at the pool, so plan on a walk of roughly 15 minutes in from the nearest lot, through the park itself. Honestly, that walk is part of the charm. Lincoln Park is beautiful, and arriving at the pool on foot, surrounded by trees and then suddenly opening up to the Sound, is part of what makes a trip to Colman feel like a small adventure rather than just a pool visit.
If this is your first trip to Colman, a little planning goes a long way toward making the day smooth. The pool gets busy fast on warm summer days, so arriving early is worth it if you want to avoid long waits for a lane or a locker. Since the facility is seasonal, it's worth checking current hours before you head out, since schedules can shift slightly from year to year.
Bring cash for lockers if you plan to use one, and come prepared for that walk in from the parking area. Comfortable shoes make a real difference, especially if you're carrying gear, a cooler, or younger kids who'll want a snack break before they even hit the water. Many regulars treat the walk itself as part of the outing, packing a small picnic to enjoy in the park either before or after their swim.
For lap swimmers, the pool typically separates lanes by speed, so there's room for both serious training and a more relaxed pace. If your goal is technique work, an outdoor 50-meter pool is also a great place to feel the difference open water style swimming makes versus a shorter indoor pool, since you get long, uninterrupted stretches to focus on your stroke without flipping a turn every 25 yards.
Plenty of Seattle families already treat a summer trip to Colman Pool as an annual tradition, and a Fourth of July visit is a natural way to start one of your own. Between the saltwater, the mountain views, and a literal birthday connection to Independence Day, it's hard to find a more fitting way to spend part of the holiday in the water.
Whether you're a competitive swimmer looking to add some open-air training variety to your week, or a family looking for a genuinely memorable way to spend the holiday, Colman Pool is worth the trip. Pack a towel, plan for that walk in from the parking lot, and give yourself extra time to enjoy the view, because the setting is honestly half the reason to go.
Outdoor swimming reminds you why you fell in love with the water in the first place. There's no better way to spend the Fourth of July than soaking up the sun, the Sound, and a little bit of Seattle history all at once.
Happy Fourth of July from all of us at Swim With Milo. However you spend it, we hope it includes some time in the water.
