Washington Park Arboretum

Washington Park is a public park in Seattle, Washington, USA, most of which is taken up by the Washington Park Arboretum, a joint project of the University of Washington, the Seattle Department of Parks and Recreation, and the nonprofit Arboretum Foundation. Washington Park also includes a playfield and the Seattle Japanese Garden in its southwest corner. The entire length of Arboretum Creek is within the park.

To the north is Union Bay; to the west are Montlake and Madison Valley; to the south is the Washington Park neighborhood; and to the east is the Broadmoor Golf Club. Lake Washington Boulevard E. runs north and south through the park, parallel to the creek. A secondary road, for most of its length named Arboretum Drive E. and for a short northern stretch named E. Foster Island Road, runs along the Arboretum's eastern edge.
