Wolf Island National Wildlife Refuge, located approximately 12 miles (19 km) off the coast of Darien, Georgia, in McIntosh County, was established on April 3, 1930 to provide protection and habitat for migratory birds. The barrier island refuge consists of Wolf Island and two smaller islands, Egg and Little Egg. Over 75% of the refuge's 5,126 acres (20.74 km2) are composed of saltwater marsh.
Wolf Island NWR was designated a Wilderness Area in 1975 and is maintained as such, with its primary purpose being to provide protection for migratory birds and such endangered and threatened species as the loggerhead sea turtle and piping plover. Due to its status as a wilderness area, no public use facilities are planned on the refuge. The refuge's salt waters are open to a variety of recreational activities such as fishing and crabbing, but all beach, marsh, and upland areas are closed to the public.
