The Stura di Lanzo has its source on the Pian della Mussa in the Ala Valley. The river flows with the name of Stura di Ala
until the village of Lanzo where, after receiving the tributary Stura di Viú, it is named Stura di Lanzo.
The no kill beat here reported is located 45 minutes by car from the city of Turin.
The regulation is strictly no kill (last info 2013). The reserve stretches from the Lanzo bridge
(after the tunnel on the "strada provinciale") to the Cafasse village.
