Overview
Des Moines Beach Park sits along the eastern shore of Puget Sound in the small city of Des Moines, Washington, roughly 20 miles south of Seattle and a short distance from Sea-Tac International Airport. The park is one of the most accessible saltwater parks in South King County, offering a gently sloping beach, a public fishing pier, a marina nearby, and picnic facilities set against a wooded backdrop.
The park occupies a natural shoreline environment where visitors can observe Puget Sound tidal activity, local shorebirds, and occasionally marine mammals such as harbor seals. It is managed by the City of Des Moines and functions as a community gathering space as well as a destination for day-trippers from across the greater Seattle metro area.
The surrounding neighborhood retains a relaxed, small-town character. The Des Moines Marina — adjacent to the park — adds additional amenities including a waterfront boardwalk and seasonal dining options. Together, the marina district and beach park form the recreational heart of the city.
Getting There
By Car
Des Moines Beach Park is located on Cliff Avenue S in Des Moines, WA. From Seattle, take I-5 south to the Des Moines exit and follow Marine View Drive S toward the waterfront. From Tacoma, take I-5 north and follow similar signage. Limited parking is available on-site; the lot can fill on warm summer weekends, so arriving early is advisable. Verify current parking fees or restrictions with the City of Des Moines.
By Public Transit
King County Metro operates bus routes that serve the Des Moines area. The park is not directly on a major route, so a short walk from the nearest bus stop is likely. Check the King County Metro trip planner (metro.kingcounty.gov) for current routes and schedules, as service can change.
By Bicycle
The area is reachable via regional trails and surface streets, though some sections of Marine View Drive have limited shoulder width. Confirm current trail connectivity through Washington Bikes or local cycling groups before planning a bike-in visit.
Things to See & Do
Beach and Shoreline
The park's gravel-and-sand beach is the main draw. At low tide the shoreline widens considerably, revealing tide pools with small marine creatures. Wading is popular in summer, though Puget Sound water temperatures remain cool year-round — typically in the mid-50s°F even in August — so extended swimming is uncommon.
Fishing Pier
Des Moines has a public fishing pier that extends into Puget Sound. No boat is required, making it a straightforward option for shoreline anglers. Common catches include perch, rockfish, and occasional salmon during runs. A valid Washington State fishing license is required for anyone 15 and older; verify current regulations at the Washington Department of Fish & Wildlife website before your visit.
Picnicking and Trails
Shaded picnic tables and open lawn areas are available throughout the park. A network of short trails connects the beach to the upland wooded sections, passing through second-growth forest with sword fern understory. The terrain is gentle and accessible for most fitness levels.
Des Moines Marina
A short walk from the park leads to Des Moines Marina, one of the larger marinas on Puget Sound's eastern shore. The boardwalk here is open to the public and provides views of docked vessels, the sound, and the Olympic Mountains on clear days. Seasonal boat launches are available; verify current fees and availability with the marina directly.
Wildlife Watching
Great blue herons, bald eagles, cormorants, and various shorebirds are regularly spotted along the shoreline. Harbor seals occasionally haul out on nearby buoys or swim close to the pier. Bring binoculars for the best experience.
Food & Drink
The park itself has no concession stands, so bring food and water if you plan a full day visit. The Des Moines Marina district, a short walk away, has a small cluster of waterfront restaurants and cafes — offerings have varied over the years, so check current options locally or via maps apps before your trip.
The nearby Des Moines city center along Pacific Highway S (SR-99) has a broader range of casual dining, fast food, and grocery options within a few minutes' drive. Chains and independent eateries alike are represented, covering most dietary preferences.
Alcohol consumption in the park is subject to Washington State and city rules — verify locally, as regulations differ between park zones and the marina.
Practical Information
Restrooms and Facilities
Public restrooms are available at the park. Verify seasonal availability with the City of Des Moines, as hours and access can vary.
Fees and Hours
The park is generally open to the public during daylight hours. Verify current admission policies, parking fees, and any reservation requirements for picnic shelters directly with the City of Des Moines Parks & Recreation department.
Pets
Dogs are commonly seen at the park; Washington State and city leash laws apply. Verify specific pet rules — including whether dogs are permitted on the beach or pier — with the city before visiting.
Weather
Des Moines experiences a mild marine climate. Summers are dry and mild (average highs 70–75°F), while winters are cool and wet. Even in summer, mornings can be overcast ('marine layer'), clearing by afternoon. Layers and a light rain jacket are practical most of the year.
Emergency Services
For emergencies call 911. For non-emergency park issues, contact the City of Des Moines directly — verify the current non-emergency number on the city's official website (desmoineswa.gov).
Safety
The park is a family-friendly, generally low-risk environment. Standard precautions apply: watch children closely near the water's edge, as Puget Sound can have cold water and unpredictable currents. The pier has railings but parents should supervise young children.
Tide awareness is important if exploring the beach at low tide — the tide can return faster than expected on flatter sections of shoreline. Consult NOAA tide charts (tidesandcurrents.noaa.gov) for the date of your visit.
The park is situated in a residential area with normal urban ambient safety levels. As with any public park, avoid leaving valuables visible in parked vehicles.
