Val Formazza

The Val Formazza (Walser: Pomattertal) is a valley in the Lepontine Alps, in the Piedmontese Province of Verbano-Cusio-Ossola, Italy.

Seven hydroelectric reservoirs were built in the valley in the 20th century: lakes Morasco, Sabbione, Toggia, Vannino, Castel, Busin, and Sruer.

[1][2][5][6] The valley is surrounded by several three-thousanders, the highest of which is the Blinnenhorn, followed by the Siedel Rothorn, Basòdino, Ofenhorn, Punta del Sabbione, Kastelhorn, Punta dei Camosci, Corno di Ban and Monte Giove.

[1][2][7][8] Two municipalities are located in the valley, Premia and Formazza, the latter of which is home to a Walser community.

[1][2][9][10] Much of the valley (22,233 hectares) is covered by a Special Protection Area as part of the Natura 2000 network.
