Several ferries run between the shore in the centre of Fort de France and 4 locations acorss the bay - Trois Islets, Anse Mitan, Anse á L´An and Point du Bout. These are all pretty touristy areas, but Anse Mitan especially is a beach hangout for locals too. The boats are pretty regular, but become less frequent in the evening, most stopping around 10 or so. Its a little more expensive than getting the bus round there, but its much much quicker! Cost is I think 38 FF return trip.
