Edinburgh effortlessly balances its weighty history with contemporary energy. The Royal Mile’s weathered cobbles lead past medieval closes and modern whisky bars, while the shopfronts of Princes Street mirror the jagged skyline of the Old Town. By day, you can hike up Arthur’s Seat for panoramas that stretch to the Firth of Forth; by evening, join the animated crowds at the Edinburgh Festival Fringe or browse the shelves of independent bookshops. Scotland's compact, hilly capital is a city where every alley holds a story waiting to be uncovered.

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.

The bright, lively capital of the Loire Valley region is nestled between two rivers: the Loire and the Cher, with the picturesque Vieux Tours old quarter lying on the long, narrow peninsula.

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.
