The Washington Park Arboretum is a 200-acre park on the shore of Lake Washington, in the Madison Park neighborhood of Seattle, with over 40,000 trees, shrubs and vines from all around the world. Start your visit at the Graham Visitors Center, where you can talk to a botanist, pick up a park map, get plant and tree lists, and find out about events, tours and facility rentals. Arboretum highlights include hiking, canoeing and kayaking, picnics, and enjoying the year-round collection of magnificent flowers, plants and trees.
The Arboretum also houses the Seattle Japanese Garden, open from February to November, a 3 1/2 acre formal garden. It features a lake with koi and turtles, community room rentals, tea ceremonies and special events all year round.
