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.

Stroll Las Ramblas and enjoy Barcelona's unique blend of Catalan culture, distinctive architecture, lively nightlife and trendy, stylish hotels. You'll find Europe's best-preserved Gothic Quarter here, as well as amazing architectural works by Gaudi. La Sagrada Familia, considered Gaudi's masterpiece, is still under construction (your entrance fee helps to fund the project). Feel like a picnic? Look no further than the rambunctious La Boqueria market, where you can stock up on local delicacies.

Tallinn's atmospheric Old Town is an enthralling hotchpotch of medieval streets and spires. It's a small city, and the tourist areas are safe and easily explored on foot. Buy a Tallinn Card if you intend to use buses, trolleybuses or trams. For a look into Tallinn's past, visit Rocca-al-Mare Open Air Museum's typical rural Estonian taverns, windmills and watermills, see the onion-domed 1900 cathedral or join the bustle in historic Town Hall Square. St Olav's spire was once the tallest in the world.

Sandy, peaceful beaches and ancient ruins beckon travelers to Chersonisos, a one-time Roman port on the island of Crete. This is a family-friendly place, with plenty of activities for kids. The Lychnostatis Open Air Museum gives you the chance to explore the trades and lifestyles of early islanders. Exhibits include a herbarium, olive oil and wine presses and workshops on ceramics, shoe making and weaving. The aquarium showcases local sea creatures, as do the town's many traditional cafes, though in a completely different (and more delicious) manner.

The dramatic and romantic desert fortress of Jaisalmer is an exotic city in Rajasthan’s great Thar Desert. "The Golden City" rose to prominence as a result of its position on camel trade routes. It's now most famous for the 12th-century fort and ornate "Havelis," fine merchant-built houses and pavilions in the city’s mediaeval lanes. The surrounding Desert National Park offers opportunities to observe blackbucks, desert foxes and chinkaras amid the rolling dunes, rugged crags and waterholes.

Laid out by British architect Edwin Lutyens, the Indian capital is a striking modern metropolis. A gracious contrast to Old Delhi's winding streets, the grand avenues and stately buildings of New Delhi are rich with history and culture, from Gandhi's Delhi home (and the site of his assassination) to the tomb of Humayun, a complex of Mughal buildings reminiscent of the Taj Mahal. Chaotic traffic is best left to the locals. Negotiate a good price for taxis or travel on the new Delhi Metro.
