Ambergris Caye is the largest island in Belize, and one of the main destinations for travellers to this Western Caribbean nation. San Pedro is the only town on the island.   This long expanse of island that was once a sleepy fishing village is now a bustling tourism destination lined with seashore developments. Fishing, coconuts, and chicle were historic means of islanders support, but the last thirty years have led to a large growth in both the Belize dive and scuba trade, and eco-tourism.
