Described by the New York Times as “a desert version of Miami's South Beach,” Scottsdale is Arizona’s biggest hit. The city is rich in culture and doesn't lack natural grandeur. The Scottsdale Arts District lends to proud attractions of galleries, studios, and museums, while architectural majesties like Frank Lloyd Wright's Taliesin West supplement the city’s Western heritage. Its position on the northern stretches of the Sonoran Desert and the McDowell Mountain Range makes the Scottsdale experience a spectacular one.

Port of Spain, the vibrant capital and the third largest city of Trinidad and Tobago, entices travellers from far and wide with its undeniable charm. Basking in a tropical climate that ensures a constant dose of hot, humid weather, this city has become a beloved hotspot for tourists seeking an all-year-round beach paradise, caressed by the gentle waves of the Caribbean Sea to the west and the Gulf of Paria to the east. With a plethora of hotels, restaurants and shops, Port of Spain promises a truly memorable experience.

Bucharest is Europe’s best kept secret. While visually it can't quite compete with other grand Eastern European capitals, it leads the pack in dynamism, energy and forward momentum. The remnants of Communism are still palpable in the urban fabric, but the city has its sights set firmly on the future. Trendy outdoor cafes and high-street shops live side-by-side with gorgeous Orthodox churches and world-class art galleries in the old town, all overlooked by the imposing Palace of Parliament.

Just 250 kilometres north of the polar circle, the summer sun shines for almost two months without going down, while the polar nights offer the most intense Northern Lights that can be seen. In Kiruna, the northernmost city in Sweden, you can go slalom skiing until midsummer or spend the night in a magnificent hotel built from ice. The phrase "kingdom of contrasts" is overused, but Kiruna truly embodies it.

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.
