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.
