Mayreau, St Vincent and the Grenadines

There are also no resorts or hotels so chances are you will be the only visitors when you go ashore for some serious sun-worshipping, swimming, snorkelling and just plain chilling out on the mile-long Saline Bay beach. This is the smallest of the Grenadine islands and you will look in vain for shopping malls, casinos or nightclubs. Mayreau is so exclusive that it is just like being on a private island and is always a highlight of any Caribbean cruise in which it features.
