Hoyt Arboretum, Portland

Hoyt Arboretum is a public living museum of trees covering about 190 acres within the hills of Washington Park. Established in 1928, the arboretum protects diverse tree species and promotes environmental education. Its collection includes more than 2,300 species from six continents and remains free to visit year-round.

More than 12 miles (19 km) of interconnected trails lead through forests, groves, and themed collections, allowing visitors to explore at their own pace. Paths pass towering redwoods, giant sequoias, magnolias, maples, oaks, conifers, and flowering trees that change with the seasons. Informational signs, guided walks, and seasonal programmes help visitors learn about trees, wildlife, and forest ecosystems.

Hoyt Arboretum is also an important habitat for birds, small mammals, amphibians, and native plants, offering a peaceful natural setting close to several cultural attractions. Woodland trails and maintained collections provide year-round interest, with routes ranging from short walks to longer hikes through one of the region's most diverse tree collections.
