The walk starts near the Ristoro Monte Scale, along the dirt road N199, and develops on a flat and accessible route suitable for everyone. The itinerary passes along the impressive Cancano and San Giacomo di Fraele dams, witnesses of the valley's engineering history: the Cancano dam, built between 1953 and 1956, receives the spill waters from the San Giacomo dam and the Viola canal, while the San Giacomo dam, started in 1940 and completed in 1950 after the war events, is fed by numerous watercourses including the Spol canal, the Alpe, Gavia, Frodolfo, Zebrù, Braulio, Forcola streams, and part of the Adda river.
The complete route includes the circuit around the San Giacomo dam, crossing the dam itself, and returning to the starting point, offering spectacular views of the lakes and surrounding mountains, especially impressive in autumn when the forests turn yellow, orange, and red.
