By Taxi -- Unmetered taxis, which you often have to share with other passengers, meet all arriving flights. They will take you to your hotel if it's on the Abaco "mainland;" otherwise, they will deposit you at a dock where you can hop aboard a water taxi to one of the neighboring islands, such as Green Turtle Cay or Elbow Cay. Most visitors use a combination taxi and water-taxi ride to reach the most popular hotels. From Marsh Harbour Airport to Hope Town on Elbow Cay, the charge is about $19. From Treasure Cay Airport, it's about $22 to Green Turtle Cay. It's also possible to make arrangements for a taxi tour of Great or Little Abaco. These, however, are expensive, and you don't really see much.
By Ferry -- Mostly, you'll get around on Albury's Ferry Service (tel. 242/367-0290; www.alburysferry.com), which provides several ferry connections between Marsh Harbour and both Elbow Cay (Hope Town) and Man-O-War Cay, a 20-minute trip to either destination. The one-way fare is $15 for adults, half-price for children 6 to 11, and free for kids 5 and under. Ferries also go to Guana Cay. The ferry docks aren't far from Marsh Harbour Airport; it's about a 10-minute, $15-to-$19 cab ride for two passengers (plus $3 for each additional passenger).
Ferries do go from Great Abaco Island to Green Turtle Cay, but those docks are a 35-minute, $80 cab ride (for up to four passengers) from Marsh Harbour Airport. To get to Green Turtle Cay, it's better to fly to Treasure Cay than Marsh Harbour; then you can take a taxi to the ferry docks.
