Forty islands make up this archipelago, with only eight inhabited. And while one island may only be a quick boat ride away from the next, each is unique, with its own set of characteristics and must sees -- from the history of Salt Cay to the iguanas on Little Water Cay, the diving on South Caicos to the nightlife on Providenciales ("Provo"). Provo is home to the 12-mile beach called Grace Bay. This is where you'll find five-star accommodations, restaurants and some of the silkiest sand in the Caribbean. While this island might be up-and-coming, you'll still find the authentic Caribbean -- great snorkeling, cozy beaches and mouth-watering seafood.
