The Arboretum provides miles of trails for exploration and contemplation. Arboretum Drive runs the length of the Arboretum from the Graham Visitor Center to the Pacific Connections Gardens. The Lookout Loop and Pinetum Loop provide interpretation of the collections and the history of the site. In late 2017, the new Arboretum Loop Trail will open, which will run along the east side of Lake Washington Boulevard and connect to the north and south ends of Arboretum Drive, completing the loop.
The Arboretum is a living collection of plants, some of high conservation value. We ask you treat this collection as you would a museum collection. Please respect and keep our plant collections and displays healthy by not climbing on trees or walking into display beds. Our horticulture staff and interactive map are available to support horticulture or plant questions you may have.
