Popular with northern hemisphere cruisers, this is where the latest and largest ships sail. Carnival Cruise Lines, Norwegian Cruise Line and Royal Caribbean have their biggest vessels sailing here, carrying millions of passengers a year to enjoy the warm weather. There are 7,000 islands to choose from, with blue seas, sandy beaches and luscious green forests. Many of the islands were colonised by the British, French or Dutch and their influences remain. From bustling Barbados and Cuba to pulsating Jamaica and St Maarten, the Caribbean is an explosion of colour mixed with the heady smell of rum and calypso music. Lines such as Disney Cruise Line and MSC Cruises even have their own private islands.
