The refuge is situated in a river floodplain that undergoes seasonal flooding, which dictates trail accessibility during the wet season.
The Tualatin River National Wildlife Refuge was established in 1992, making it one of the few urban national wildlife refuges in the United States.
More than 200 species of birds have been documented within the refuge boundaries.
The refuge's 'Friends of Tualatin River NWR' organization actively manages a native plant nursery on-site for restoration projects.
The visitor center building itself achieved LEED Gold certification for sustainable design and operation.
Tualatin River National Wildlife Refuge is a 1,856-acre preserve located within the Portland metropolitan area along the Tualatin River. The site features the two-mile Wetland Discovery Trail, which is fully accessible and includes floating boardwalks over riparian habitats. The refuge serves as a vital stopover for migratory waterfowl, including Canada geese, wood ducks, and tundra swans. The visitor center provides interpretive exhibits regarding the Willamette Valley’s historical oak savanna and wetland ecosystems. Wildlife observation is facilitated by several viewing platforms and blinds positioned along the trail network. The refuge protects diverse habitats, including wetlands, bottomland hardwood forests, and upland prairies. Research and restoration efforts are ongoing to maintain the water quality and biodiversity of the Tualatin River basin.

Bring binoculars as the viewing platforms offer excellent vantage points for spotting elusive raptors and waterfowl.
Check the official website for current trail closure alerts, as heavy seasonal rain often floods the lower sections of the boardwalks.
Use the 'all-access' paved trail near the visitor center if you have limited mobility or are traveling with a stroller.
Attempting to hike off-trail or venturing onto closed boardwalks during the wet season, as this risks environmental damage and personal injury.
The Wildlife Refuge trails are typically closed on Mondays and Tuesdays to minimize human disturbance to wildlife.
Stay strictly on marked trails to protect sensitive wildlife habitats; dogs and other pets are prohibited on the refuge trails.
