Bridgetown is the capital and largest city of the nation of Barbados. It is the only city on Barbados and well over half the island's residents live there. It is the port of call for many cruise ships and is known for its duty-free shopping as much as for its more cultural and historical attractions.

Saint Kitts and Nevis are a pair of tropical islands in the Caribbean and the smallest sovereign state in the Americas, in both area and population. The country is a Commonwealth realm, with the British Monarch (currently, Elizabeth II) as its head of state.  Saint Kitts and Nevis were among the first islands in the Caribbean to be settled by Europeans. It was home to the first British and French colonies in the Caribbean, and thus has also been titled "The Mother Colony of the West Indies''. The natural aspect is what makes the country remarkable. Many tropical birds which one rarely finds elsewhere are present in great concentration in the nature and there are also the famous monkeys which, it is said, were introduced by the pirates

One of the major tourist areas in St. Lucia, Castries, is a port of call for cruise ships. They dock at Pointe Seraphine, to the north of the harbour, which is also a duty-free shopping centre. Beaches are also a major draw for tourists, and there are several in or very near Castries. The city doesn't have a huge amount to offer visitors, and it's usually just a place that you'll pass through on your way to the more obvious attractions of Saint Lucia - but it's worth watching those marvellous cruise ships that visit Saint Lucia dock!
