Belize is a small but incredibly diverse country, with dense jungle to the west and Caribbean seas to the east. For divers, it doesn’t get better, as there are more than 400 islands, the longest unbroken barrier reef in the western hemisphere and 185 miles of coastline. Head out to the Great Blue Hole spearfish for your lunch in the Turneffe Atoll; come face-to-face with sharks in coral reefs; and enjoy lunches on hidden beaches. Moving inland, take a helicopter to a luxury jungle lodge, visiting incredible Mayan ruins, caves and waterfalls en route.
