With beautiful white sand beaches, excellent dining and a plethora of outdoor pursuits, Floridian Naples truly has it all, and more awaits outside the city limits at the Everglades National Park downstate or – closer yet – the Ten Thousand Islands National Wildlife Refuge. Naples is also known for its first-rate golf courses and deluxe boutiques, both of which give the city a well-off, prosperous air.

In 1831, Charles Darwin sailed to South America aboard the H.M.S. Beagle. On the return voyage across the Pacific, the vessel stopped on a small group of islands far off the Ecuadorian coast, changing the course of human scientific endeavour and self-understanding forever. Fascinated by the unique wildlife on the islands, Darwin collected biological specimens and studied them over the next 30 years. His findings led to the formulation of the scientific theory of evolution by natural selection. This small group of islands and their one-of-a-kind wildlife are to thank for one of humanity's most remarkable discoveries. And today, almost 200 years later, they remain a source of endless fascination and a favourite travel destination for scientists, nature and wildlife enthusiasts, scuba divers, and anyone interested in the wonders of the natural world.

South African Durban, known as eThekwini in Zulu, has to be one of the continent's most appealing cities, especially after the 2010 World Cup breathed new life into the area by revamping the waterfront; the splendid Moses Mabhida Stadium remains one of Durban's primary attractions to date. Durban moves to the beat of gqom, its own home-grown music genre, which is slowly making its way onto global charts from South Africa's sunny, tropical melting pot of eclectic cultural influences.

The narrow and often steep granite-paved streets of Cagliari’s Castello District are a reminder of a bygone age when the town was dominated at first by Pisans, and later by the Aragonese. Built from white limestone, the walls and towers of the Old Town shimmer in the sun and are a magnificent sight, especially if you are lucky and approach the city from the sea, as the English novelist D.H. Lawrence did in 1921 when he described the Old Town as looking like a "Jerusalem without trees".

Primarily known as a financial hub, George Town is also a prime destination for cruise ships. The capital city of the Cayman Islands is just 10 minutes away from the long crescent of the famous Seven Mile Beach with blindingly white coral sand. There is no better place to enjoy submarine and glass-bottom boat tours, try snorkelling, scuba-diving or parasailing. Get your credit card ready for some serious tax-free shopping, and don't leave without trying the remarkable sunken rum.
