Austria is 83,879 km², and its nine states fall into two kinds of trip. Vienna, Lower Austria and Upper Austria lie along the Danube on level, easily crossed ground, with Vienna alone holding 1,931,593 of the country's roughly nine million people. Tyrol, Salzburg, Vorarlberg and Styria are the Alpine states, entered by valley rather than by plain, and their capitals — Innsbruck, Salzburg, Bregenz, Graz — are each small enough to cross on foot in an afternoon. The distinction decides an itinerary: the Danube cities sit an hour apart by train and the mountain ones do not.
