Marsh Harbour is a town in Abaco Islands, Bahamas, with a population of 5,314. With more than five thousand residents, Marsh Harbour is the third largest town in The Bahamas, and the main focus of tourism in the Abacos. Marsh Harbour is a shipbuilding center, but tourism accounts for most of its revenues. A number of inns are located here. Although the town is not as large as New Plymouth or Hope Town, it does have a shopping center and various other facilities not found in many Out Island settlements. Good water-taxi connections, as well, make this a popular place from which to explore offshore cays, including Man-O-War and Elbow." Boat rentals are available, as are bicycles and motor bikes.
The settlement lies on a peninsula just off the 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. Marsh Harbour has the majority of services available in all of the Abacos, including a post office, bookstore, grocery stores, specialty shops, travel agencies, and laundries. Visitors come to boat, swim or snorkel, and stay at one of the lodges located near Bay Street on the waterfront, though some adventurers reserve a day or two to kayak in the Marls on trips conducted by naturalist guides.
