The British Virgin Islands or simply the "Virgin Islands", part of a volcanic archipelago in the Caribbean, is known for its reef-lined beaches and as a yachting destination. The BVIs, as they are called, are a popular travel destination for sailors, fishermen, sun worshippers, and other independent travellers, albeit not for the cost conscious. Boating among the dozens of tiny, mostly uninhabited, islands is a great stop on any tour of the Caribbean islands.
