Immortalized by Hemingway in “Islands in the Stream,” Cayo Guillermo is perched on Cuba’s north coast between the Bay of Dogs and the Atlantic. It is home to four all-inclusive resorts. Five miles of fine white sand and gorgeous, clear green waters, including the spectacular Playa Pilar, offer picture perfect sunning spots. Fantastic snorkeling and scuba diving opportunities beckon from more than six miles of coral reefs. Flamingos and many other birds live in its lagoons, forest and jungle.

It’s a UNESCO World Heritage Site and a fantastic home base for a visit to the Valley of the Sugar Mills, a pocket of land that formerly served as the centre of Cuba’s sugar industry.

Travelers come to this small island north of mainland Cuba to bask in the sun, swim in sparkling blue water, and be pampered at an all-inclusive resort.

The nearby Tulum Monkey Sanctuary will put you in a playful mood.

The Dominican Republic lies in the same waters as Cuba and Puerto Rico, taking up the eastern two-thirds of the island it shares with Haiti.

There's more than one way to enjoy the spa experience in St. Lucia. One is to book a treatment at any of the luxury spas or resorts on the island.

"For simple beauty, Cape Breton outrivals them all." So said Alexander Graham Bell of the island he adopted as his home.
