Olhuvelii Island, Dhaalu Atoll,
Forty minutes southwest of Malé by seaplane, this popular resort appeals to a youthful crowd with such amenities as an indoor gaming center and large in-room fridges—the better to take advantage of the on-site deli. After a day of water sports, excess energy can be expended in the gym or on the dance floor—two DJs keep the nightlife pulsing, spa treatments are available 24/7, and there's a large infinity pool for recuperating during the day. Quieter pastimes include sunset sails in a picturesque dhoni and snorkeling over the coral nursery with the resident marine biologist: For a donation of $40, you can pick out a coral to name and plant on a new reef, and receive progress reports on your progeny for the following year. Doubles from $700.
