British West Indies
This might just be the most stunning stretch of sand—coupled with a warm, cerulean sea—in the world. The fact that it's an Aman just makes it even better. Like all its counterparts around the world, the resort essentially disappears into the surroundings, but in the most luxurious way. For one, it's set far away from the (very busy) Eastern part of the island. And for two, the rooms are simple and pristine. Besides a great spa and excellent food, there's tennis, reef diving, and plenty of other thrills to fill the days.
