While Stuttgart may not be at the top of most travel itineraries, southwestern Germany's largest city is well worth a few days' visit. In a lush valley ringed with vineyards and thick forests, Stuttgart may well be the greenest city in Europe. Nearly 20% of the city is under a land preservation order, and the citizens pride themselves on their environmentalism. Best known as the home of Porsche and Mercedes-Benz, Stuttgart is also one of Germany's premiere wine-growing regions, and its many mineral spas are a draw for relaxation seekers as well as seniors taking 'the cure.'

With its moderate climate, proximity to the Black Forest and unique Swabian heritage, Stuttgart is a great place to experience an authentic German city without hordes of tourists. There's plenty of culture, too: The Staatsgalerie (State Gallery) is notable for both its Picasso collection and its architecture, the Stuttgart Ballet and the International Bach Academy enjoy worldwide renown, and the city boasts the highest number of bookshops per capita of any German city. For a raucous time, visit during the Cannstatter Volksfest (People's Festival), Germany's second-largest Oktoberfest celebration (after Munich). If you'd prefer a more low-key vacation, there are plenty of vineyards and parks to explore, or head for one of the local spas and soak in a mineral bath.
