With nearly 1,200 islands spread over a chain of 26 atolls, the Maldives are popular with tourists seeking serene beaches, scuba diving, and surf in the Indian Ocean. The atolls, like those pictured on our homepage, are made up of coral reefs that formed around the top of now-sunken volcanoes. Some are single, ring-shaped islands enclosing lagoons while other atolls are a series of small, connected islets, many of which are uninhabited.
