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.
