This isolated island property is a dream destination for scuba divers. Not only is the area home to intricate coral reefs that ring the numerous islands, but visitors can also swim with dolphins, manta rays and whale sharks — the largest fish in the world. Guests arrive at this luxurious Indian Ocean outpost via seaplane and enjoy classic Four Seasons amenities, such as fine dining, a top-notch spa and depending on room selection, private plunge pools. We recommend the water villas, with glass bathroom floors for up-close views of life in the peaceful lagoon. For fledging divers, certification programs are offered through the resort's PADI Five-Star Gold Palm Dive Centre. Families can even join in, as introductory programs are offered for kids as young as eight.
