A private island 6km (3 3/4 miles) from Union Island in the southern Grenadines, this speck of land is rimmed with white-sand beaches. On 45 hectares (111 acres), it's an out-of-this-world corner of the Caribbean that's only for self-sufficient types who want to escape just about everything.

The easiest way to get to Petit St. Vincent is to fly to Union Island via St. Vincent. Make arrangements with the hotel to have its "PSV boat" pick you up on Union Island. This is the southernmost of St. Vincent's Grenadines.
