Alto Adige (German: Südtirol), officially the Autonomous Province of Bolzano/Bozen – South Tyrol, is a province in northern Italy.
Together with Trentino, Alto Adige forms the autonomous region of Trentino-Alto Adige.
It is Italy’s northernmost province, bordered by Switserland in the west, Austria to the north and northeast, Lombardia (Sondrio) in the southwest, Trentino in the south and Veneto (Belluno) in the southeast.
The province’s landscape is dominated by mountains.
The highest peak is the Ortler (3,905m) in the far west, which is also the highest peak in the Eastern Alps outside the Bernina Range.
Even more famous are the craggy peaks of the Dolomites in the eastern part of the region.
The main valley is the Adige valley which runs from Merano to Rovereto via Bolzano and Trento.
There are too many Trentino valleys to mention, but among them are the Vallagarina, the Val di Sole, the Val di Non (which extends both in Trentino and in South Tyrol), the Valsugana, the Martello Valley, the Gardena Valley and the Badia Valley.
Map with passes and dead ends in Alto Adige – if a summit appears outside the area, one end of the climb will start in it, and the other end in the neighboring area.
