The Argentinian capital, Buenos Aires, is a city like no other. It has a hint of a European feel but with a distinctly Latin American flavour. It is cosmopolitan yet autochthonous. Every street corner and narrow alleyway is teeming with art and culture, history and personality, tango, rock 'n' roll, and football. It is a city of museums, galleries, classical-style cafes, world-class steakhouses, antique markets, bookstores, and midnight strolls along the majestic River Plate.

Drop anchor in Karlskrona, the city founded in 1680, when Charles XI decided to build the country's new naval base here. 340 years later, the naval base remains, and the well-preserved architecture and city plan impressed Unesco, which gave Karlskrona World Heritage status in 1998. Wherever you go, you can see magnificent churches and squares, parade streets and fortifications that attract visitors from all over the world. All this on several islands in an archipelago that Unesco has designated as one of seven biosphere reserves in Sweden.

Nestled between the imposing Al Hajar Mountains and the salty waters of the Arabian Sea is Muscat, the cosmopolitan Omani capital. Now home to almost half the country's population, the city is an expat's darling and has a lot to offer in the way of historical sights, culture, and entertainment. Muscat has managed to remain relatively concealed from the touristic eye and retains a sense of inwardness and an unspoiled quality long lost by some of its Emirati neighbours.

Edged by mountain ranges, Canberra is a planned city built on vast limestone plains. Canberra is Australia’s national capital — the seat of the Federal Parliament and home to many institutions and national monuments. Four distinct seasons add to its charm, and visitors quickly discover that it really is Australia’s hidden gem. The surrounding countryside contains historic and picturesque rural villages and a burgeoning cool-climate wine industry.

Olbia is the gateway to the pearly white beaches of Sardinia's northeast coast and the sparkling Costa Smeralda. This is where jet-setters, film stars and the ‘glitterati’ arrive to indulge in 'la dolce vita' Sardinian-style. With a Greek name meaning ‘happy’, Olbia used to be a little fishing village but has now grown to become Sardinia’s busiest ferry port, complete with an international airport and tons of tourist amenities. The countryside is cloaked in aromatic wild herbs, the macchia, and the surrounding sea glows in every hue of electric blue, in a little known and exclusive place waiting to be discovered.
