A tiny drop of granite rock, tropical foliage and crystalline sand in the Indian Ocean is home to this blow-the-budget private island resort. Here, the lofty prices open up a world of abundant birdlife overhead and a host of mystical-sounding dive sights in the emerald waters below. Guests can plunge to Monument Valley, spend time scouring Grande Anse Reef or brave the shadowy depths of Barracuda Rock. More sedentary pursuits include sunset cruises, dining in one of four gourmet restaurants, unwinding in the Rock Spa or relaxing in your secluded private villa.
