Strung below craggy mountains, the Omani capital of Muscat is one of the Middle East’s oldest and most picturesque cities. Between its corniches and modern quarter are Portuguese-built forts, blue-domed mosques, royal palaces, and souks, all heavy with the sense of a lost Arabia.

From the cosmopolitan metropolis of Cebu City and the white-sand beaches of Mactan to the electric-blue waters of Kawasan Falls and the whale sharks of Oslob, it’s easy to see why Cebu Island is one of the Philippines’ top destinations.

Lying in south central Turkey, the moonscaped region of Cappadocia, southeast of Ankara, is most famous for unique geological features called fairy chimneys. The large, cone-like formations were created over time by erosion of the relatively soft volcanic ash around them. Past cultures have dug into them to create dwellings, castles (like Uchisar) and even entire underground cities like Kaymakli and Derinkuyu, used as hiding places by early Christians. Nearby Kayseri is the gateway to the area.

Kas may be known as Turkey's premier scuba diving destination, but with its ancient ruins, oceanside restaurants, and bougainvillea-covered houses boasting Ottoman-style balconies, the seaside town offers more than just underwater pursuits.

Bristling with beautiful lakes, splashing rivers, rugged peaks and looming castles, Vorarlberg is tucked between Switzerland and Germany. This spirited state is dotted with Bauhaus-inspired architecture, eco-friendly dwellings and tiny towns, bristling with spires. Capital Bregenz is the main draw in this alpine locale. Cobblestone streets and a lovely lakeside setting add to its charms. Renowned for its cheese and dairies, Vorarlberg is also a popular spot for skiing and other winter sports.

The 1000-year-old Norwegian capital sits at the head of Oslo Fjord. This stunning setting gives hints of the wild wonders that lie just beyond the city. From taking in visual delights at Vigeland Sculpture Park, the Viking Ship Museum, the Munch Museum and Holmenkollen, to the challenging content within the new Nobel Peace Centre and the Holocaust Centre, Oslo offers plenty of food for thought. The Oslo Pass allows free travel on public transport, free parking and many museum and sight admissions.
