Marsh Harbour / Abaco is the third largest city in the Bahamas. Although Marsh Harbour is the center of commerce for the Abacos, it is like stepping back in time here. There are no malls or department stores, no drive-thrus, and no neon lights. They actually do have the only stop light on the island. It also has many excellent seafood restaurants, gift shops, boutiques, native crafts galleries, and duty free shops. But don't forget that the island has all the beautiful white-sand beaches with all the usual water sports.
