South Andros is a district of the nation of the Bahamas. Geographically, South Andros is the southernmost third of the land mass colloquially called Andros, which includes the districts of North Andros, Central Andros, Mangrove Cay and South Andros. The districts are divided by broad unspanned "creeks", some of which offer public ferry crossing; otherwise the only way to travel from one district to another is by private plane or boat. South Andros is accessed from Nassau via commercial airline (currently two trips daily from Nassau to Congotown International Airport), from the U.S. via two flights commercially from Fort Lauderdale International and other islands by charter airplane (usually from Fort Lauderdale, Florida), and from anywhere by private boat. A public ferry runs daily between South Andros and its northern neighboring Mangrove Cay which is also considered a part of South Andros. The mail boat comes to Andros once a week from Nassau, leaving Nassau Monday night and arriving at Driggs Hill port on South Andros on Tuesday morning, which brings the majority of all imports and supplies to the island, from milk to petrol.
