Ambergris Caye is the largest island in Belize, and the main destination for travellers to this western Caribbean nation. San Pedro is the only town on the island. Ambergris Caye has been the hub of Belizean area maritime trade for centuries. Fishing, coconuts, and chewing gum 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 ecotourism. The rich variety of things to do in San Pedro Town makes Ambergris Caye the gateway to Belize.
