Long isolated from the outside world, Bhutan is a relic of a more traditional Asia, preserved in time and with little in the way of tourist infrastructure. In an increasingly connected world, this small, beautiful, and utterly enchanting Himalayan country is one of the last truly off-the-beaten-path destinations on the planet. It is a challenging country to visit, but to those who choose to venture there, it soon reveals itself to be an especially rewarding one, as well.

Charismatic seaside Catania is a young, dynamic soul, inhabiting a body of narrow alleys and ornate Baroque buildings set atop well-preserved remains of ancient Greek and Roman settlements. Mount Etna defines the cityscape both in terms of the striking panorama and the building material — Catania is even referred to as the "grey city" for the colour of lava rocks used to construct many of its buildings.

Porto was once the last stop of adventurers on their way across the Atlantic to the New World. The cliché that Lisbon shows off and Porto just works is a well-worn metaphor that fails to do justice to the city's innumerate charms fully. History dwells around every corner, and more than ever, Porto is a place determined to hold on to its own distinct identity.

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.
