Long known for its old-world charm, from the historic Faneuil Hall to the Freedom Trail that celebrates Boston’s preeminent role in the American Revolution, Boston has come a long way towards staking its claim in the 21st century. With the completion of the “Big Dig” that buried Boston’s vast network of highways underground, Boston has hit the new century running. Attractions span beautiful public libraries, fascinating museums and plenty of sports. Boston is destined to grow ever more beautiful as more and more of the ungainly elevated highways are replaced with lush parks.

Still relatively rural, Sedona emerges as one of America's natural masterpieces. Magnificent red rocks extend upwards as natural skyscrapers, while clear waters flow around them. Native Americans thrived in the area before the arrival of Europeans, and now both national and international visitors come to see the astonishing landscapes of the city. Sedona is commonly known for being a spiritual retreat destination.

Bogotá is the sprawling, high-altitude capital of Colombia. Cradled by chilly and lush Andean peaks, the city features the colonial-era historical centre La Candelaria. Colonial buildings and cobblestone streets attract visitors to explore the Pre-Columbian Gold Museum, Fernando Botero's art and ornate churches. Bogotá’s monumental government buildings and human-scale brown brick houses are a real treat for architecture lovers. Another major attraction is the city's vibrant and varied nightlife.

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.
