The full guide

In summer, a diving platform sits anchored out in a small bay on Lake Washington, and at the park's southern end Thornton Creek slips quietly into the lake. This is Matthews Beach Park, a 22-acre city park on the west shore at 5100 NE 93rd St in Seattle's Matthews Beach neighborhood, and one of the city's popular spots for summer swimming, with lifeguards on duty. The park stays open through the colder months, too.

Swim the Lake

The swimming beach is the heart of Matthews Beach Park and the main reason people come. Wade in from the shore while Seattle Parks and Recreation lifeguards keep watch through the summer, then, if you are a stronger swimmer, set your sights on the diving platform anchored out in the lake beyond the shallows.

Both the lifeguards and the platform are seasonal, so plan your swim for the summer months. Check with Seattle Parks and Recreation before you go for this season's lifeguard schedule.

Picnics, Barbecues and a Playground

Give yourself a full afternoon here rather than a quick dip. Spread out at one of the several picnic tables and fire up a barbecue pit for an easy lakeside cookout, remembering to bring your own food and supplies.

When the kids need a break from the water, head to the playground. Locker rooms give swimmers a place to change before and after time in the lake.

Ring In the Year With a Polar Bear Plunge

Matthews Beach Park draws a crowd even in winter. Every New Year's Day, Seattle Parks and Recreation sponsors a Polar Bear Plunge here, and participants wade into the chilly lake to start the year off bracingly. Because the park is open year-round, it also makes a lovely setting for a quiet winter walk along the shore.

Where Thornton Creek Meets the Lake

The park curves along a small bay on Lake Washington in a residential area. Its western edge borders the Burke-Gilman Trail, so you can walk or cycle straight in from the path, while the eastern side holds Matthews Beach itself, the stretch of shoreline that gave the park its name.

Stroll to the southern end to see where Thornton Creek flows into Lake Washington. The surrounding neighborhood shares the beach's name and is part of the larger Lake City district, and our Matthews Beach neighborhood guide covers the area in more detail.

From Duwamish Village to City Park

People have lived along this shoreline since the last glacial period. The communities around Lake Washington were known as the People of the Large Lake, part of the Duwamish Tribe and speakers of Lushootseed, and a village called too-HOO-beed stood near what is now Thornton Creek, close to present-day Matthews Beach and Meadowbrook.

In the 1880s, a pioneer named John G. Matthews set up a homestead near the beach, and both the park and the neighborhood carry his name today. The land joined the Seattle Parks and Recreation system in 1951.
