Firefly Mustique

Below the four-poster bed of your Tree House room at hillside Firefly Mustique, white yachts bob in the reef-fringed turquoise bay. At dusk, the view of the Caribbean horizon from the patio is thrilling. You can also enjoy that vista in the shower, whose floor is made of sea pebbles. Under your feet, the smooth stones feel as delicious as one of Mustique's white-sand beaches.

Tiny and unspoiled, the private island of Mustique is a playground for the likes of Princess Margaret and Mick Jagger. Laid-back Firefly Mustique keeps things exclusive by offering just five rooms with amenities such as iPods, beach baskets, and 250-thread-count Italian linens. In the property's tropical gardens, you'll find two waterfall-fed swimming pools, as well as a stable full of horses for rides along the beach.

Come sundown, dine à la carte on the ocean-view terrace. And don't be surprised if you meet a celebrity at the piano lounge, which is famous for its martinis and Champagne cocktails.
