Trentino-Alto Adige is made up of two provinces, the Italian-leaning Trento (or Trentino) in the south and the Germanic-leaning Alto Adige (or Südtirol, and also called Bolzano-Bozen, just to keep things interesting) in the north. Home to numerous picturesque towns, castles and historic sights, the main attraction here is the mountains. The stars of these are the Dolomites. Outdoor adventure opportunities abound year-round, with skiing, climbing and hiking among the most popular pursuits.
