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 189 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 2,000 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!

Support the Trees in Arbor Month

We don’t just celebrate Arbor Day at Hoyt Arboretum. We celebrate Arbor Month!

During Arbor Month we put extra effort into nurturing our 6,000 trees and celebrating our living museum. You can join the celebration with a tax-deductible donation that helps maintain our world-class plant collection.

Thanks to a very generous supporter, your contributions will be matched up to $12,000, so your gift has double the impact! Your investment in Portland’s free urban green space will help purchase new plants, maintain our 12 miles of trails, and fund youth education programs that are creating tree stewards for the future. Join our cause and help make Hoyt Arboretum even better by donating online at www.hoytarboretum.org/donate.

Not a member of Hoyt Arboretum Friends? Your first-time gift of only $25 makes you a member with benefits including discounts at the Visitor Center Nature Store, for classes and from arborist companies and nurseries. Enjoy reciprocal member benefits at nearly 300 gardens and arboretums, and much more.

We deeply appreciate your continued support of Hoyt Arboretum and invite you to join us by celebrating Arbor Month and supporting the trees.
