The islands of the Caribbean Sea or West Indies are an extensive archipelago in the far west of the Atlantic Ocean, mostly strung between North and South America. They've long been known as a resort vacation destination for honeymooners and retirees, but a small movement toward eco-tourism and backpacking has started to open up the Caribbean to more independent travel. With year-round good weather (with the occasional but sometimes serious exception of hurricane season in the late summer and early fall), promotional air fares from Europe and North America, and hundreds of islands to explore, the Caribbean offers something for almost everyone.
The Caribbean islands were first inhabited by the Arawak Indians, then were invaded by a more aggressive tribe, the Caribs. Unfortunately, neither could appreciate their victory forever, although the Arawaks may have had a quiet reign of nearly two millenia. Then the Spanish, Portuguese, Dutch, French, Danish, and British arrived, after which the Carib population steeply declined due to various factors. The islands have known many historic battles and more than a few pirate stories.
Cuba, Dominican Republic, Haiti, Jamaica, Puerto Rico and the Cayman Islands, often grouped as Greater Antilles, are by far the largest countries in the area and the most visited by travellers. In the north is the Lucayan Archipelago, which includes The Bahamas and the Turks and Caicos Islands. The Caribbean also includes the Lesser Antilles, a group of much smaller islands to the east. Further to the west and south, there are various less frequently visited islands that belong to Central and South American countries.
