About 10 miles north of Nuremberg, Erlangen is the home of the University of Erlangen-Nuremberg (Friedrich-Alexander-University), founded in 1742. Just over 100,000 people live here, about a third of whom are involved with the university; about another third work for the Siemens corporation. Bergkirchweih, Erlangen’s annual festival - akin to Munich’s Oktoberfest - opens in a different beer cellar every year and is attended by over a million people in its twelve-day run around Pentecost.

With half a million people, Nuremberg is Bavaria's second largest city. While its history dates to the 11th century, Nuremberg is most often linked to the 20th century (specifically World War II). It first served as the site of many pre-war Nazi rallies, then was nearly levelled by Allied bombing, then was the site of the famous post-war Nuremberg Trials. The city has much to offer today's visitors, including the rebuilt Nuremberg Castle and the world-famous gingerbread at Hauptmarkt. Hansel and Gretel would have loved this place.

Walk atop Rothenburg’s city walls or climb to the top of the town hall for great views. The Night Watchman tour is an unforgettable way to learn the city’s history. And our travelers also recommend the Medieval Crime Museum (Mittelalterliches Kriminalmuseum)—it’s gruesome but fascinating.

Like Rothenburg, Dinkelsbuehl is one of the smaller mediaeval fortress cities. With its walls and towers still intact, it has the look of a typical German town of the 15th to early 17th century. Sample the famous German cuisine served in larger cities, but without the crowds. Don't miss the annual summer celebration, marking the city's surrender to Swedish troops during the Thirty Years' War. The event is emphatically reenacted by many of the town's residents. And really, who doesn't love amateur theatre?

Amsterdam is truly a biker’s city, although pedaling along the labyrinthine streets can get a little chaotic. Stick to walking and you won’t be disappointed. The gentle canals make a perfect backdrop for exploring the Jordaan and Rembrandtplein square. Pop into the Red Light District if you must—if only so you can say you’ve been there. The Anne Frank House is one of the most moving experiences a traveller can have, and the Van Gogh Museum boasts a sensational collection of works.

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.

It’s nicknamed the Eternal City for a reason. In Rome, you can drink from a street fountain fed by an ancient aqueduct. Or see the same profile on a statue in the Capitoline Museum and the guy making your cappuccino. (Which, of course, you know never to order after 11 am.) Rome is also a city of contrasts—what other place on earth could be home to both the Vatican and La Dolce Vita?

Edinburgh is Scotland’s capital city, renowned for its heritage, culture and festivals. Take a long walk around the centre to explore the World Heritage Sites of the Old Town and New Town, as well as all the area’s museums and galleries. Then stop for a delicious meal made from fresh Scottish produce before heading out to take in one of Edinburgh’s many events — including the famous summer festivals of culture, or the Winter Festivals of music, light and ceilidhs.

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.

You've probably heard that Guinness tastes better in Dublin (fresh from the factory), but what you may not know is that Dublin is a perfect destination for the whole family. No, we're not suggesting you let the kiddies drink a pint. Instead, take them to the Dublin Zoo, to feed the ducks in Stephen's Green or on a picnic in Phoenix Park. Scholars enjoy walking in the literary footsteps of such writers as Yeats and Joyce, while discerning shoppers have their pick of designer boutiques.

When 13th-century Portuguese Queen Isabel passed through Obidos and marveled at its beauty, her husband King Denis I simply gave it to her. For centuries after, the kings of Portugal followed suit, presenting the picturesque little town to their queens as a wedding gift. With its white buildings shining as brightly now as then, the walled city of Obidos is very popular with tourists, its hillside location offering amazing views of the Estremadura area. The medieval castle is a main attraction.

The fishing town of Tavira combines two Mediterranean staples: Moorish architecture and a golden beach. Here, a labyrinth of cobbled streets winds past houses tiled in the traditional Portuguese style, and the pace of life flows as gently as the Gilão River.

The biggest resort town on what's called the "Russian Riviera," Sochi is preparing to step onto the world stage as the host of the 2014 Winter Olympics. Somewhat ironically, Sochi is really quite temperate for most of the year, with its Black Sea waters warm and swimmable well into October. The Arboretum and Riviera Park are among the city’s most popular destinations. Serving as a beautiful backdrop for Sochi are the Caucasus Mountains, home to the nearby snow skiing resort of Krasnaya Polyana.
