Divers and snorkellers will be in their element in this small Central American country - the 150-mile Belize Barrier Reef offers some of the best diving and snorkelling in the world. There are also Mayan ruins to visit in the jungle, notably at Altun Ha, which dates back to 900BC.
Take me there: Norwegian Cruise Line has a seven night cruise calling at Belize from £1,040pp, based on two sharing, including flights.
