Bodie Island is a long, narrow barrier peninsula that forms the northernmost portion of the Outer Banks. The land that is most commonly referred to as Bodie Island was at one time a true island, but in 1811 Roanoke Inlet, which had separated it from the Currituck Banks in the north, closed. As a result, the Currituck Banks and Bodie Island are now one contiguous peninsula, joined at the Nags Head area, where the inlet once flowed. Today, either name can be used to refer to the peninsula as a whole, but both portions colloquially retain their historical names.
