Matthews Beach Park is steeped in local history, named after pioneer John G. Matthews, who established his homestead on the site in the 1880s. Long before European settlement, the area was inhabited by the hah-choo-AHBSH, "People of the Large Lake," a group of the Duwamish Tribe who lived near what is now Thornton Creek. The park's land also played a significant role in early 20th-century aviation, serving as the offices and dock for Pan American World Airways' "Clipper Ships," the world's first amphibious commercial air transports, in the 1940s. Despite initial opposition from the Parks Department, the City of Seattle officially acquired the first ten acres of Matthews Beach in 1951, thanks to the persistent efforts of community clubs and activists who recognized the site's immense value as a public green space.

What to do here

Enjoy swimming and sunbathing on the beach, picnic with family and friends, walk or bike along the Burke-Gilman Trail, launch hand-carry boats like kayaks and canoes from the designated sandbar, and engage in birdwatching.
