Marsh Harbour is a city in Abaco Islands, Bahamas, with a population of 5,314. Home to more than five thousand residents, Marsh Harbour is the third largest town in The Bahamas and the main focus of tourism in the Abacos. Featuring most of the hotels, inns, marinas and diving operations on the island, the town is an essential hub for ferries connecting with the rest of the Loyalist Cays. The settlement lies on a peninsula just off the smoothly paved Great Abaco Highway, which runs south through Great Abaco to Cherokee Point and Little Harbour. North of town, the road becomes S.C. Bootle Highway, another smooth stretch that runs north and west toward Treasure Cay and Little Abaco.
