An expansive beach resort on Bulgaria's Black Sea coast, lively Sunny beach appeals to young international travellers for its sand dunes, watersports, and thrumming nightlife. Clubs and bars draw crowds of merrymakers, while an amusement and water park offer daytime entertainment.

Mamaia is a popular beach resort on the coast of the Romanian Black Sea. The fine white sand beaches are unusual for this part of the world, so tourists flock here during the summer months for a tropical experience that’s close to home. Crush Beach is great for people-watching and water spots. At night, the area throbs with club goers and beautiful party people.

We hear the question, "What’s the next Prague?" a lot. But while we’re all for discovering great new destinations, we hardly think Prague is over. Sure, everyone’s heard of it, but it’s still a grand city with extraordinary historic and cultural sights, and it’s definitely worth a visit. The often-rebuilt Prague Castle has overlooked the city since the 9th century, and the synagogues and cemetery of the Jewish Quarter are must-sees. Nightlife here is diverse and plentiful, from trendy clubs to sophisticated wine bars to late-night cellar bars.

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.

Translating to "Monday" in Tajik, Dushanbe was once a tiny mountain village known for its Monday market. Today that village has become a metropolis, but the Barakat covered market remains one of the most vibrant attractions in the city. Dushanbe's wide, tree-lined avenues are home to a number of monuments and museums, including the Unified Museum and the Museum of Antiquities, as well as a beautiful opera theater and myriad cafes and teahouses where visitors can sample Tajik sweets.

Move over, Haussmann and l'Enfant. Beijing's urban planner beat you by a couple of centuries. His name is Kublai Khan. Here, you'll find a wealth of history, both ancient (the Hall of Preserving Harmony, Summer Palace, Forbidden City) and more recent (Chairman Mao Memorial Hall, Tienanmen Square). For the best market experience, choose the Dirt Market over the touristy Silk Market.

The charming Vietnamese capital has aged well, preserving the Old Quarter, monuments and colonial architecture, while making room for modern developments alongside. Hanoi may have shrugged off several former names, including Thang Long, or "ascending dragon", but it hasn't forgotten its past, as sites such as Ho Chi Minh's Mausoleum and Hoa Lo Prison attest. Lakes, parks, shady boulevards and more than 600 temples and pagodas add to the appeal of this city, which is easily explored by taxi.

Bangkok is full of exquisitely decorated Buddhist temples—as you go from one to the next you’ll be continually blown away by the craftsmanship and elabourate details. But if you’d rather seek enlightenment in a gourmet meal, or dance the night away, you’ll also enjoy Bangkok—the restaurant and nightclub scenes here are among the best in the world.
