Many people travel through Frankfurt for business, as it's a major transportation hub and an industrial and financial metropolis. Of course we know that business travellers hate to have any fun on the road (wink), but it's worth lingering in Frankfurt if you can. The 2,000-year-old city has much to offer: skyscrapers, the Main River, a famous opera house, thriving theatre district, zoo, pedestrian shopping street, parks, scores of bars and dance clubs, and more than 50 museums.

In progressive Berlin, the old buildings of Mitte gracefully coexist with the modern Reichstag. Don't miss top historical sights like the Berlin Wall, Checkpoint Charlie, the Brandenburg Gate and Potsdamer Platz.

The capital of North Rhine-Westphalia, Dusseldorf is a regional economic powerhouse straddling the banks of the Rhine River. Altstadt is not just Dusseldorf's lovely old town, but also where the city's nightlife is based and where Altbier, its native dark beer, is plentiful. Dusselforfians take their beer seriously. Königsallee (Ko to the locals), Dusseldorf's famous shopping street, has many high-end stores. And the Museum Kunst Palast has one of the Rhineland's best art collections.

Munich was almost completely destroyed in two world wars, yet it's managed to recreate much of its folkloric, Bavarian past. Oktoberfest is legendary, but you can visit the Hofbrauhaus any time of year for an immense beer. Olympiapark, the site of the 1972 games, is not to be missed (you can skate on the Olympic ice rink and swim in the pool). On a somber note, take time to visit the concentration camp at Dachau—it's an intense, yet unforgettable, glimpse into the not-too-distant horrors of the Holocaust.

Second only to Berlin in size and population, the city of Hamburg is home to one of the biggest harbours in Europe. A stroll along its many waterways and canals illustrates why it has been called the "Venice of the North." Don't miss a trip to the local fish market (Fischmarkt), the Merchants District (marked by its imposing red-brick architecture), a fine dining experience along the river or a night out in the university quarter. And did we mention the Reeperbahn (red light district)? It's quite famous for its… red lights.

Surrounded by one of Germany's largest wine-growing regions, Stuttgart beckons cultural junkies with its acclaimed ballet, opera and philharmonic, while car fans get revved up over the Mercedes Benz Museum. There's more green space than urban sprawl in the festival-friendly city, home to Europe's largest combined zoo and botanic garden, the Wilhelma. The Württembergisches Landesmuseum, in one of the city's oldest structures, traces the area's history from the Stone Age. Buses or metro provide handy transport.

Though probably best known as the capital of West Germany from 1949 to 1990 (and of reunified Germany until 1999), Bonn actually has a history dating back to the 1st century BC. Roman soldiers were stationed here and the largest known Roman fort was built at Bonn. In medieval times, the town gained prominence when the Archbishop of Cologne transferred his seat to Bonn. The city's most famous son is Ludwig van Beethoven, born in 1770 at Bonngasse, where a museum now honors him.

From Hannover’s atmospheric old town, filled with reconstructed half-timbered buildings and terrace cafes, to its baroque gardens and vast urban lake, this booming city has much more to offer than its industrial reputation suggests.
