Located midway on the Georgia coastline on the eastern fringe of McIntosh County, Sapelo Island is defined by the Sapelo River to the north, the waters of Doboy Sound to the south, the Atlantic Ocean to the east, and the Duplin River to the west. The 16,500-acre island is the 4th largest barrier island in the State of Georgia.

The Sapelo Island National Estuarine Research Reserve (SINERR), located on the western perimeter of Sapelo, is dedicated to research, education, stewardship, and sound management of coastal resources in Georgia. Specifically, this facility focuses on the natural, cultural and historical resources of Sapelo Island and the Duplin River estuary.

SINERR, one of 26 reserves around the country, is administered by the National Oceanic and Atmospheric Administration (NOAA) and managed by the Georgia Department of Natural Resources, Wildlife Resources Division.

In an effort to provide the best information to the public, the SINERR website recently received a complete overhaul - check it out at  Sapelo Island National Estuarine Research Reserve
