Daufuskie Island, located between Hilton Head Island and Savannah, is the southernmost inhabited sea island in South Carolina. It is 5 miles long by almost 2.5 miles wide – approximate surface area of 8 square miles (5,000 acres). With over 3 miles of beachfront, Daufuskie is surrounded by the waters of Calibogue Sound, the Intracoastal Waterway and the Atlantic Ocean. It was listed as a census-designated place in the 2020 census with a population of 557.
Accessible only by ferry or barge, and with a full-time population of just over 400, Daufuskie Island contains environmental preserves, private communities, resorts, Gullah houses, diverse art galleries and history. The island was named a historic district on the National Register of Historic Places due to its Gullah and Civil War history. The island is also the setting of Pat Conroy's memoir The Water Is Wide recounting Conroy's experiences teaching on Daufuskie in the 1960s. ~ the above taken from Wikipedia
