Petit St. Vincent is a 113-acre private island resort framed by two miles of pristine white sands that is one of the best couples resorts in the Caribbean. The lack of room TVs, phones, and even planned activities is especially appealing for those who want to indulge in their most luxurious private island fantasy. Choose from beachfront cottages, complete with alfresco living and dining areas, some of which sit on a bluff overlooking the sea. Should you wish complete privacy, just hoist your red flag, which signals staff to stay away. If you hoist the yellow one, you’ll probably receive whatever your heart desires, from a lift to the beach bar to food and drink. You can use the same system at the beach, just raise the yellow flag and you can have a picnic lunch, or drinks brought right to your hammock. The full-service spa offers Balinese massage, and you can also enjoy sailing, kayaking, diving, fishing trips, hiking, yoga, and more.
