Groveland Beach Park

SE 58th Street and 80th Ave SE

Groveland Beach is a 3-acre park featuring a concrete bulkhead, swimming beach, pier, sand volleyball court, and playground. The City acquired the property, which was originally a summer camp for religious groups, in 1965 and developed the beach park in 1967. As Mercer Island’s only west-side beach, Groveland sees high visitation in the summer months, including during the annual Seafair summer festival.
