Welcome to Hoyt Arboretum

At Hoyt Arboretum, every tree has a story to tell. Founded in 1928 to conserve endangered species and educate the community, Hoyt Arboretum encompasses 190 ridge-top acres, accessible by 12 miles of hiking trails. A place of beauty and serenity in all seasons, Hoyt Arboretum is easily accessible from anywhere in the Portland metropolitan area by car, bus or the MAX light rail. A free shuttle is available in Washington Park from May through October. You will also find parking, restroom facilities, ADA accessible trails and ADA parking at or near the Visitor Center. 

An arboretum is a promise to future generations. Just as we are enjoying mature and wonderful trees that were planted many years ago, the trees we plant today will grow to provide shade, beauty and value for decades and centuries to come. More than 6,000 specimens from around the world grow here, including more than 2,300 species, 63 of which are vulnerable or endangered. Hoyt Arboretum is a living laboratory where anyone can enjoy trees and plants that are both familiar and unexpected.

Visit Hoyt Arboretum today and enjoy Portland's museum of living trees!
