Zurich is Switzerland's largest city, a major transportation hub, and a top starting point for travelers. The city lies at the northwestern end of Lake Zurich astride the river Limmat. Beyond its buttoned-up façade, this affluent banking capital boasts a rich line-up of cultural treasures. A great place to begin a walking tour is the cobbled streets of the Old Town with its quaint shops, cafés, and galleries. Mile-long Bahnhofstrasse, one of Europe's finest shopping strands, beckons with designer stores selling fashion, watches, and jewelry.
