Back Bay National Wildlife Refuge was established on June 6, 1938 as a 4,589-acre refuge to provide feeding and resting habitat for migratory birds.
Back Bay NWR includes a thin strip of barrier island coastline typical of the Atlantic and Gulf coasts, as well as upland areas on the west bank of Back Bay. Habitats include beach, dunes, woodlands, agricultural fields, and emergent freshwater marshes. The majority of refuge marshes are on islands within the waters of Back Bay. Back Bay NWR provides over eight miles of scenic trails, a visitor contact station, interpretive programming and, with advance scheduling, group educational opportunities.
