Stuttgart

Set in a lush valley ringed with vineyards and thick forests, Stuttgart may well be the greenest city in Europe. The citizens pride themselves on their environmentalism. Stuttgart is also one of Germany's top wine-growing centres, and its many mineral spas are a draw for relaxation seekers.

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. For a more raucous time, visit during the Cannstatter Volksfest, Germany's second-largest Oktoberfest celebration.
