From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.

Although originally known as a summer destination, when the first snowflakes land in St-Moritz, so do the international scenesters, bundled up in the latest "must-have" accessories. In winter, take a ride on the Glacier Express from Zermatt to arrive in style. Cable cars ascend to three nearby mountain tops. Hundreds of miles of ski trails and a frozen lake comprise the area's most popular sports venues. Follow the Romans' example and try one of the city's mineral springs, such as St-Moritz Bader.

Corsica is a laid-back French island, with a breezy vibe that’s part European weekend and part tropical honeymoon. The port city of Bastia flings its arms wide open to weary travelers disembarking from a long ferry trip. For a truly charming Corsican experience, catch a train through the mountains to the beach, passing by rustic villages and grazing cows along the way. Take a few hours or even a few weeks to explore the island’s famous walking trails, including the varsity-level GR 20.

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.

The prophet Mohammed's birthplace is Islam's spiritual center and is strictly off-limits to non-Muslims. The pillars of Islam state that all Muslims with the means must undertake Hajj, a pilgrimage to Mecca, once in their lifetime. Those who visit the holy city are rewarded not just by proximity to landmarks and religious sites crucial to the religion, such as the Masjid Al Haram (Holy Mosque), the Mountain of Light, the Black Stone and the Well of Zamzam, but with the forgiveness of all their sins.
