16 Most Beautiful Islands in the World

The Maldives are home to some of the world's most ravishing islands, but it's the sea, which truly makes these islands shine. Luminous aquamarine waters with a crystal clarity lap upon these dazzling white shores, which barely peek above the Indian Ocean. Consisting of 26 natural atolls, the Maldives archipelago is the planet's lowest lying nation, rising no more than three meters above the sea at its highest point, a measurement that shrinks every year. Beneath the mesmerizing waters, coral reefs flourish, luring divers and snorkelers from around the world. Surfers also flock here to ride the uncrowded breaks. Back on land, luxury resorts provide the perfect launching points for adventures focused upon the sea, the archipelago's greatest asset, but also, as the planet's climate changes, its single greatest threat.

Shaped like a giant sombrero, this lush volcanic island stars in countless South Pacific fantasies.
