Lanzo Valleys

The Lanzo Valleys (in Italian Valli di Lanzo, in Piedmontese Valade ëd Lans) is a group of three valleys in the north-west of Piedmont in the Metropolitan City of Turin, Italy. They are located in the Graian Alps of Piedmont, between the Valle dell'Orco to the north and the Val di Susa to the south. Crossed by various streams which in each valley is called Stura and which flow into the river Stura di Lanzo, the valleys take their name from the town of Lanzo, located on an ancient glacial moraine at the end of the valleys.

Etymology
The valleys take their name from the city of Lanzo, which lies in the main valley near its exit on the Po Plain.

Geography


The Lanzo Valleys (in Italian Valli di Lanzo, in Piedmontese Valade ëd Lans) are a group of valleys in the north-west of Piedmont in the Graian Alps of Piedmont, between the Valle dell'Orco to the north and the Val di Susa to the south. The most important sub-valleys are, from south to north and from west to east,
 * 1) Valle di Viù (literally ''Valley of Viù) with its main centers Viù, Lemie, Usseglio.
 * 2) Val d'Ala (literally Valley of Ala) with its main centers: Ala di Stura and Balme.
 * 3) Val Grande (literally Great Valley), with its main centers of Cantoira, Chialamberto and Groscavallo.
 * 4) Val Tesso (literally Valley of Tesso, named after the Tesso a left-hand tributary of Stura di Lanzo)

The Val Grande di Lanzo joins the Val d'Ala in Ceres; from here the two valleys descend joined through the villages of Mezzenile and Pessinetto; in the municipality of Traves they join the Valle di Viù and from here the 3 valleys continue together as one.

The Stura di Lanzo, a tributary of the Po, collects the waters flowing through the valleys.

Other municipalities of the area are Germagnano, Monastero di Lanzo and Coassolo Torinese.

Access
The valleys can be reached by the Po Plain either by railway, with the Ferrovia Torino-Ceres, or by road, following the strada provinciale n.1 named "Direttisima delle Valli di Lanzo".

The valleys of Lanzo are closed valleys, that is, they do not have Alpine passes connecting them with France and nearby Italian valleys. There are 3 exceptions:

 * 2) the Colle della Dieta, which connects the hamlet Asciutti di Viù with the hamlet of Monti di Mezzenile,
