The Alder Island Nature Trail is a short (0.5 mile), easy walking trail that winds along the Siletz River and Millport Slough.
The surface is natural soils and gravel. It is not accessible to wheelchairs. It's open from sunrise to sunset and is a wonderful place to look for songbirds and waterfowl.
Access the trailhead by turning east off of U.S. Highway 101 onto Millport Slough Lane and into the refuge parking lot.
Dogs are prohibited on the nature trail.
