Located around the town of Ridgefield, Washington, this wildlife refuge is a great place to see throngs of wintering Tundra Swans, Canada Geese, Sandhill Cranes and many raptors. The River S unit, located south of town, is an auto tour route but offers two stops in winter and an additional one in summer where birders can get out and scope the area. Restrooms at two stops. During May-September pedestrians are allowed on the road but the rest of the year the marked stops are the only places to get out and scope. Two of the stops are wheelchair accessible. 28908 NW Main Ave. WA 98642 The Carty Unit, located just north of town, offers a 2-mile trail through oak groves and past wetlands where a variety of songbirds can be found.
