We recommend you fly on American or U.S. Air from Ft. Lauderdale, West Palm Beach or Miami to Marsh Harbor, Great Abaco Island. Although there are a number of other independent airlines now serving this island.   Don't forget your passport or birth certificate! Also, keep in mind there are restrictions on the kinds of foods you can bring into the Bahamas, with specific restrictions on poultry. In Marsh Harbor, a taxi will take you to Albury's Ferry dock. Taxi drivers will recommend places to shop for food and other supplies you may want -- although there are grocery, hardware, clothing and gift stores in Hopetown.
