About Hoyt Arboretum
Portland’s museum of living trees, Hoyt Arboretum thrives thanks to a long-term partnership between Portland Parks & Recreation and the nonprofit Hoyt Arboretum Friends. With over 6,000 trees and 12 miles of trails free and open to the public year-round, the Arboretum is maintained by a dedicated community of volunteers and members. A beautiful destination for recreation, it’s also an important resource for education, research, and conservation.
A place to hike among and appreciate global tree diversity, a center for research and conservation, and a community treasure – Hoyt Arboretum is many things to many people. Learn what makes this place special.
The member-driven nonprofit that supports education, volunteer, and conservation efforts at the Arboretum, Hoyt Arboretum Friends keeps the Arboretum thriving and provides opportunities for the community to participate in its care and cultivation.
From a 19th century poor farm, to a nationally recognized home for over 6,000 trees and a community treasure for generations, this place has changed a lot over the decades.
A team of Portland Parks & Recreation and Hoyt Arboretum Friends staff work together to keep the Arboretum and its programs thriving, and our all-volunteer Board of Directors and Advisory Council provide governance and support.
