Swim Area
Located in the Puget Sound region of Washington, this swimming area is about 15 kilometers southeast of Seattle, on the shores of Lake Washington. The body of water, formed by glaciers during the last ice age, covers over 87 square kilometers and is one of the largest lakes in the state. The surrounding shoreline alternates between wooded areas and residential sectors, with generally gentle and accessible shores, characteristic of lakes in the American West. This swimming area shares the calm waters of Lake Washington with several other water recreation sites. At 3.8 kilometers is Mercer Island Beach Club Beach, more oriented towards private clubs, while another similar swimming area exists 4.2 kilometers away. The site offers direct access to the water without specific supervision, in a tranquil atmosphere typical of the inland lakes of the Pacific Northwest. The waters remain cold even in summer, reflecting the influence of the glacial springs that feed the lake. Access to the site does not have Blue Flag status. No shower, toilet, or parking facilities are reported in the available data. Swimming is done without lifeguard supervision. Visitors should anticipate their equipment needs and check local access conditions before their visit, particularly regarding parking and basic facilities.
About this spot
Lake Washington, named after the first American president George Washington, served for a long time as a main transportation route for the indigenous Duwamish and Salish peoples before the arrival of European settlers in the 19th century. The opening of the Ballard Locks in 1917 lowered the lake level by more than two meters, permanently reshaping its shoreline and transforming accessible swimming areas. Unimproved swimming areas like this one retain the informal character of lake recreation in the Northwest, where local residents have frequented the shores for generations to escape the marine humidity of the Pacific coast.
