Wind River Arboretum
Southwest WashingtonBest Apr–Oct
A 1912 arboretum with 250 tree species on loop trails through the oldest research forest in the PNW.
About This Trail
The Wind River Arboretum is the oldest arboretum in the Pacific Northwest, established in 1912 as part of the Wind River Experimental Forest. Connected loop paths form a 2-mile interpretive trail through a collection of roughly 250 tree species from around the world, including Giant Sequoias near the historic Forest Service buildings.
Fourteen large interpretive signs and individual species placards line the route, making this more of a walking classroom than a typical trail. The canopy overhead is the main event: look up. Spring brings wildflowers to the understory, and the low elevation (1,200 feet) keeps the trail accessible when higher-country options are snowed in. That said, snow does reach the arboretum some winters, particularly in March.
The site sits within the Wind River Administrative Site Historic District near Carson, WA. Old Forest Service buildings dot the surrounding area. WTA work parties have been restoring the long-abandoned trail system as part of the Lost Trails Found campaign. No parking pass is required, and the trailhead rarely sees crowds.
