The Oregon Coast National Wildlife Refuge Complex consists of six National Wildlife Refuges along the Oregon Coast. It provides wilderness protection to thousands of small islands, rocks, reefs, headlands, marshes, and bays totaling 371 acres (150 ha) spanning 320 miles (515 km) of Oregon's coastline. The areas are all managed by the United States Fish and Wildlife Service.
The six National Wildlife Refuges—three marine, and three estuarine—are from Tillamook Head south to the California-Oregon border. The marine refuges are Three Arch Rocks, Oregon Islands, and Cape Meares. The estuarine are Bandon Marsh, Nestucca Bay, and Siletz Bay. Except for Tillamook Rock Light and its surrounding 1-acre (4,000 m2) rock, all the islands are closed to public access. Boats must remain at least 500 ft (150 m) away, and aircraft must maintain at least 2,000 ft (610 m) clearance.
Three Arch Rocks National Wildlife Refuge was the first National Wildlife Refuge west of the Mississippi River. The refuge has provided protection for Oregon's largest seabird nesting colony of more 230,000 birds since October 14, 1907.
