The Grenadines, a chain of idyllic tropical microdots, extend for more than 50 miles south of the dramatic volcanic island of St. Vincent. Many of the smaller islets are uninhabited. World-famous as a sailing ground, the Grenadines also offer some of the most inviting beaches in the Caribbean. Perhaps the most interesting of all the islands is Bequia, where, for centuries, the inhabitants have constructed distinctive wooden boats and interisland schooners. The island’s main town, Port Elizabeth, has a superb natural harbor, well known among yachtsmen around the world.
