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.

If Saigon is the frenetic, commercial heartbeat of Vietnam, then verdant and historic Hanoi is the sedate, intellectual soul of the country. Its leafy boulevards, serene lakes, and sweeping white French colonial architecture set the scene as tourists and locals go about their business at a pleasingly civilised pace.

The iconic white sand island archipelago, washed by crystal-blue waters of the Indian Ocean, firmly holds on to its reputation as a sought-after luxury holiday retreat for vacationers the world over. Earlier heralded as primarily a honeymoon destination, the Maldives now draw a diverse range of travellers to its increasing number of backpacker inns and long-established high-end resorts.

The beating heart of the Indian state of Gujarat, Ahmedabad has managed to preserve its cultural integrity through the centuries, remaining relatively unaffected by British colonial rule. Little developed by the tourism industry, the city remains a true hidden gem inhabited by remarkably hospitable Gurajatis, teeming with exquisite historic temples, renowned universities, and world-class vegetarian eateries able to convert diners of the most carnivorous persuasion.
