The largest city in Switzerland, Zurich is a major contemporary art and shopping destination. Important artworks are displayed in the Kunsthaus and the Rietberg Museum, while those who consider shopping an art can hone their skills along Bahnhofstrasse and Niederdorf. Chagall's stained glass windows in the Fraumunster amaze, and Zurich's 500 clubs and bars—including several in swimming pools—pulse with life 'til the early hours. This city on Lake Zurich has excellent public transit and a free bike rental system.
