Peavy Arboretum is at 8692 N.W. Peavy Arboretum Rd. Managed by Oregon State University’s College of Forestry, Peavy Arboretum features a trail network winding among a variety of trees, including giant sequoias, redwoods, dogwoods, oaks, pines and firs. Wildflowers bloom in spring, and the leaves of American chestnut, California hazel and walnut trees blaze with color in fall. Signs throughout the arboretum describe tree species and area history.
