Most people moving to the Seattle metro don't think of Des Moines as a waterfront city. Then they drive down Marine View Drive S and realize the city sits on six uninterrupted miles of Puget Sound shoreline — more accessible public beach than most King County cities three times its size. That geography shapes everything: what you do on weekends, where neighbors gather, and why people who moved here for the airport commute end up staying for the lifestyle.
The shoreline isn't just scenery. Within city limits you get a 900-slip working marina, two public fishing piers, a two-lane boat launch, a 137-acre state park, a designated whale-watching site, and a nearly 20-acre historic waterfront park — all free or low-cost to access. For a city of roughly 33,000 people, that is an unusual concentration of public outdoor infrastructure, and it's the main reason recreation features so prominently in conversations about what daily life here actually feels like.
Inland, the Des Moines Creek Trail connects the waterfront to the wooded corridor near Seattle-Tacoma International Airport, and the city's parks complex at Des Moines Beach Park adds tennis courts, a skate park, and indoor gym space for year-round use. Youth sports and organized activities run through the Highline Public Schools district and local programs — worth reviewing if you have school-age kids who'll rely on league sports and after-school programs.
Whether you're already committed to moving here or still weighing Des Moines against Burien or Federal Way, the sections below cover the signature parks, the waterfront access points, the trail network, and the seasonal rhythms that define outdoor life in this city.
The Waterfront Parks: Des Moines Beach Park and Saltwater State Park
Des Moines Beach Park at 22030 Cliff Ave S is where the city's public life centers. The nearly 20-acre park holds 635 feet of saltwater beach, open meadows, second-growth woodland trails, and a salmon-bearing stream that runs directly into Puget Sound. The Covenant Beach Historic District within the park is listed on the National Register of Historic Places — so when you're spreading a blanket on the lawn for a summer evening, you're doing it on historically significant ground.
The park is also the city's main event venue. Every Wednesday night from July 15 through August 19, 2026, the free Des Moines Summer Concert Series takes over the park — a genuinely local tradition that draws mixed crowds of longtime residents and newcomers who've just figured out that this spot exists. If you want to get a read on the community quickly after moving in, this is the most efficient way to do it.
Beyond the beach, the park complex includes the Des Moines Beach Park Event Center (a 4,000-sq-ft indoor field house gym) and the Des Moines Activity Center at 5,448 sq ft, plus a picnic shelter, tennis courts, and a skate park. These facilities stay open through the colder months when the beach crowds thin out, giving the park a year-round utility that purely seasonal waterfront parks lack.
Saltwater State Park: The 137-Acre Gem With a Catch
Saltwater State Park adds 137 acres and 1,445 feet of Puget Sound beachfront to the city's recreational inventory. Sandy swimming beaches, rocky tidal pools, and forested ravine trails along McSorley Creek — a salmon-spawning stream — make it a genuinely different experience from the manicured setting at Des Moines Beach Park.
The underwater dimension sets it apart from any other park on the Sound. Saltwater State Park contains Washington's only underwater artificial reef, designated as a Marine Protected Area and consistently listed among Puget Sound's top scuba diving sites. On a clear summer morning you'll find drysuits being unzipped in the parking lot alongside families setting up for a beach picnic.
One thing to know before you plan an overnight: as of March 24, 2026, the campground is closed due to flooding and erosion damage, with no reopening date announced. Day-use areas remain open 8 a.m. to dusk. If you were counting on camping here as a selling point for visiting family, plan around that reality for now.
| Park | Acreage | Beach Frontage | Key Features | Cost |
|---|---|---|---|---|
| Des Moines Beach Park | ~20 acres | 635 ft saltwater | Historic district, trails, gym, skate park, tennis, summer concerts | Free |
| Saltwater State Park | 137 acres | 1,445 ft saltwater | Scuba reef, tidal pools, McSorley Creek trails, swimming beach | Discover Pass (day use) |
| Des Moines Beach Park Event Center | Indoor, 4,000 sq ft | — | Field house gym, rentable event space | Fee for rentals |
| Des Moines Activity Center | Indoor, 5,448 sq ft | — | Multi-use recreation facility | Program fees vary |
| Des Moines Creek Park | Wooded corridor | — | Trailhead for Des Moines Creek Trail, riparian forest | Free |
| Redondo Beach Area | Shoreline | Boardwalk + pier | Fishing pier, boat launch, whale watching, MaST Aquarium nearby | Free / launch fee |
The range from a free neighborhood beach to a state-managed diving reserve — all within a single city — is the clearest illustration of what makes Des Moines's outdoor offering so hard to replicate at this price point.
The Marina and Redondo Beach: Life on the Puget Sound Waterfront
Des Moines Marina is not a decorative amenity. It's a working, full-service facility with approximately 900 slips, wet and dry moorage for up to 850 vessels, and 1,500 feet of guest dock space accommodating boats up to 100 feet. Permanent in-water slips (20 to 50 feet) are offered month-to-month with a two-month minimum lease — unusual flexibility for a marina of this size. There's a fuel dock carrying gasoline, diesel, and propane, a free pump-out station, shore power, and showers.
For non-boaters, the marina is still a destination. The public fishing pier gives you open-water access without a vessel, and the marine atmosphere along Marine View Drive S — where Wally's Chowder House on Marine View Drive S anchors the waterfront dining scene — makes this stretch one of the more genuinely active shoreline areas in the South Sound.
What people discover after six months here: the marina area is dramatically more active on weekday evenings than most suburban waterfront parks. Dog walkers, joggers, anglers, and marina residents create a baseline of foot traffic that feels more like a small coastal town than a Seattle suburb.
Redondo Beach: Whales, Piers, and a Free Aquarium on Saturdays
About two miles south of the marina, the Redondo Beach neighborhood anchors a different kind of waterfront experience. The 670-foot concrete-and-aluminum pier at 28201 Redondo Beach Dr S — built in 1980 and one of the longer public fishing piers on the Sound — draws anglers year-round, but the wildlife watching is what surprises newcomers most.
Redondo Beach is a designated Whale Trail site. Resident orca pods J, K, and L are most commonly visible from October through February; gray whales pass through occasionally in spring and summer. Seals, sea lions, and river otters are common enough to be almost routine. Nobody moves to Des Moines expecting to spot an orca from a city pier, and yet it happens here regularly.
The MaST Center Aquarium, located near the boardwalk, runs free Discovery Days every Saturday with touch tanks and exhibits of native Puget Sound species — including a 38-foot gray whale skeleton. It's the kind of low-key Saturday morning activity that families with young kids end up building a weekly habit around, and it's genuinely free.
The two-lane public boat launch at Redondo serves trailered vessels and supplements the marina's launch facilities, giving the area a practical utility beyond the scenic appeal.
Trails: The Des Moines Creek Trail and the Lake to Sound Connection
The Des Moines Creek Trail runs 2.2 miles on a paved, wheelchair-accessible surface from near Seattle-Tacoma International Airport south through wooded Des Moines Creek Park, ending at the marina. It handles bikes, inline skates, and foot traffic — and because it's paved and mostly flat, it's genuinely usable for the full range of fitness levels, not just dedicated cyclists.
The wooded canyon section through Des Moines Creek Park is what makes the trail feel longer than 2.2 miles. Second-growth forest closes in on both sides, the creek runs below the trail in places, and the airport fades acoustically within a few minutes of entering the tree canopy. It's a meaningful natural buffer in a built-up suburban corridor.
The Bigger Picture: Lake to Sound Trail
The Des Moines Creek Trail is also a segment of the developing Lake to Sound Trail, a regional multi-use corridor intended to connect Lake Washington to Puget Sound across the southern King County landscape. The full route is still being built out, but the Des Moines segment is among the more complete and maintained stretches already in place.
For commuters, the trail's northern terminus near Sea-Tac creates an interesting edge case: a small number of airport and nearby office workers actually use it as a bicycle commute route, though this is a secondary use rather than the trail's primary draw.
| Trail / Route | Length | Surface | Best For | Access Points |
|---|---|---|---|---|
| Des Moines Creek Trail | 2.2 miles | Paved | Nature Commuter | Near Sea-Tac Airport; Des Moines Marina |
| Des Moines Beach Park trails | Short loop | Natural surface | Families Nature | 22030 Cliff Ave S |
| Saltwater State Park trails | Ravine loop | Natural surface | Nature Quiet | Off Marine View Drive S, south Des Moines |
| Redondo Beach Boardwalk | Shoreline walk | Paved boardwalk | Walkable Views | 28201 Redondo Beach Dr S |
| Lake to Sound Trail (partial) | Regional (in progress) | Paved (Des Moines segment) | Commuter Nature | Multiple; Des Moines Creek Trail is current anchor |
| Marine View Drive S waterfront walk | Informal | Sidewalk / shoulder | Walkable Views | Along marina and downtown waterfront |
One honest limitation: the trail network is concentrated near the shoreline and creek corridor. If you live in the Star Lake or North Hill neighborhoods, the nearest trailhead requires a drive, and sidewalk continuity in the inland areas is inconsistent.

Seasonal Recreation: What Changes Quarter by Quarter
Des Moines doesn't have a traditional off-season in the way that mountain towns do, but recreation here shifts substantially between summer and winter. Understanding that calendar before you move is the difference between loving the city year-round and finding it gray and limiting from November to March.
Summer (June–September): The City Earns Its Reputation
Summer is when Des Moines justifies every comparison to a small coastal town. The swimming beaches at Saltwater State Park and Des Moines Beach Park fill on warm weekends. The marina guest docks see steady traffic from boaters running up and down Puget Sound. The free Wednesday concert series at Des Moines Beach Park runs through mid-August. Fishing from the Redondo and marina piers peaks. Kayak and paddleboard launching from the beach areas becomes a daily routine for residents who discover the sport after moving in.
One summer quirk newcomers underestimate: weekend parking at Saltwater State Park and Redondo Beach fills by 10 a.m. on sunny days from late June through August. If you don't live within walking distance of these spots, adjust your timing expectations — or own a bike and use the Des Moines Creek Trail to reach the marina.
Fall (October–February): Wildlife Watching Peaks
The orca pods return to the inner Sound in October, and the Redondo Beach pier becomes one of the better free wildlife-watching spots in King County. Salmon runs in McSorley Creek at Saltwater State Park and the stream at Des Moines Beach Park draw both fish and the birds that follow them. Stormy weather creates dramatic wave conditions along the boardwalk that photographers and storm-watchers seek out specifically.
Scuba diving at Saltwater State Park's artificial reef is a year-round activity but the visibility in fall and winter is typically better than in the plankton-heavy summer months — a counterintuitive seasonal draw that the local diving community takes seriously.
Spring: Salmon Runs, Gray Whales, and the Return of the Crowds
Gray whales appear occasionally in the waters off Redondo in spring on their northward migration, which makes the pier worth a scan even on overcast mornings. The parks begin to reactivate — the skate park at Des Moines Beach Park sees consistent use once temperatures stabilize, and the trail network picks up foot traffic as the days lengthen.
Worth noting for anyone planning around the Saltwater State Park campground: as of mid-2026 it remains closed with no announced reopening timeline. Day-use access is unaffected, but if overnight camping was part of the pitch you were making to yourself or your family, check the Washington State Parks site for current status before making plans.
| Season | Best Activity | Where | What to Know |
|---|---|---|---|
| Summer | Swimming, concerts, boating, fishing | Beach Park, Marina, Saltwater SP | Parking fills early on sunny weekends |
| Fall | Orca watching, salmon viewing, diving | Redondo Pier, Saltwater SP, Beach Park stream | J/K/L pods most visible Oct–Feb |
| Winter | Storm watching, scuba diving, pier fishing | Boardwalk, Saltwater SP reef, Marina pier | Better dive visibility than summer |
| Spring | Gray whale sightings, trail running, skate park | Redondo Pier, Des Moines Creek Trail | Gray whales occasional on northward migration |
| Year-round | MaST Aquarium (free Saturdays) | Redondo Beach area | Touch tanks, 38-ft gray whale skeleton, no cost |
| Year-round | Marina walking, boardwalk jogging | Marine View Drive S, Redondo Boardwalk | Active foot traffic even on gray days |
The residents who get the most out of Des Moines are the ones who stay curious about the water in every season — not just the ones who show up in July and leave before the orcas do.
Local Expert Takeaway: Des Moines, WA fits more public waterfront into a small city than most South Sound residents realize — six miles of Puget Sound shoreline, two fishing piers, a 900-slip marina on Marine View Drive S, a scuba reef inside city limits, and a free aquarium at Redondo Beach on Saturday mornings. The Des Moines Creek Trail connects the wooded inland corridor to the waterfront in 2.2 miles, and the Wednesday concert series at Des Moines Beach Park gives summer a weekly social anchor. The catch: the Saltwater State Park campground has been closed since March 2026 with no reopen date, inland neighborhoods require a drive to reach most of this, and summer parking at Redondo Beach fills before 10 a.m. on sunny days. Know the rhythms and you'll use these parks constantly. Ignore them and you'll wonder why you pay Seattle-adjacent taxes in a suburb that doesn't feel like it has much going on.
