The Ridgefield National Wildlife Refuge offers over 5,000 acres of vital migration and wintering habitat for spring and fall migrating birds. The mild winter climate and wetlands along the Columbia River create ideal resting and feeding areas for 180 species of birds such as Canada Geese, Sandhill Cranes, Great Blue Herons, swans, shore and song birds, and a variety of waterfowl. Visitors can see these and other magnificent wildlife while driving the 4-mile auto tour or hiking along the two-mile Oaks to Wetlands Wildlife Trail year-round.
