The artificially made Freeport Peninsula, constructed by making a causeway between several small lagoon islands (the Bogue Islands) in the 1960s, is located southwest of downtown Montego Bay and serves, among other functions, as the docking point for cruise ships, a nexus for the yachting crowd, and home to the city's two most centrally located all-inclusives (including the posh Secrets resort).
It’s a bit of a hike from downtown, but worth the walk/drive for drinks at the yacht club or dinner at the Houseboat Grill that floats amid the mangroves of the Bogue Lagoon.
