Historic Mountain Routes | Toce waterfall-Riale-Passo San Giacomo road

The road starts from the Toce waterfall and the route is characterized by hairpin bends and reduced slopes, flanked by stone walls and arches from which you can take unique photos of the Riale plain and the peaks of Alta Formazza. After this first stretch of climb, the road continues on a slight slope crossing the basin of Alpe Toggia, reaching the Maria Luisa refuge and skirting the dam of Lake Toggia. The climb increases to reach Passo San Giacomo, where already in 1885 there was a small shelter where telegraphers stayed and from which a beautiful view opens up over the Swiss Val Bedretto (Switzerland). Here new fortifications were built in the 1930s which became the heart of the defense system of the homonymous pass: the "Grandinagia" artillery fort and the "San Giacomo" armored fort.
