A long route with continuous ups and downs that starts from Montalto Pavese, climbs to Belvedere, and then passes through Montù Berchielli, Pometo, Passo del Carmine, Ruino, and finally reaches Lago Trebecco in the province of Piacenza.

SIGNAGE: 201

Montalto Pavese is located in the lower area of the Oltrepò Pavese Mountain Community, south of Pavia, on the valley of the Ghiaia stream. It is called the "queen of Oltrepò Pavese" for its dominant position on the first hills above Casteggio, its beautiful castle with Italian-style gardens, and its wine production. The Belvedere area, located on the ridge of a hill and exposed to strong winds, is a popular destination for tourists and enthusiasts of paragliding and model aircraft.

Shortly after Belvedere, following the yellow bicycle sign leading to the unmistakable Big Bench of Montalto Pavese, you can enjoy a breathtaking view of the surrounding hills.

After passing the giant bench, from which the Montalto Pavese castle can be seen, you enter a wild area with no trees, where, with a bit of luck, you may encounter some roe deer.

The route continues up and down hills and vineyards until reaching Passo del Carmine, located at around 600 meters above sea level in the municipality of Colli Verdi, an important crossroads, as it is at the start of several valleys.

Passo del Carmine also represents another important boundary, between the mountainous Oltrepò and the wine-producing Oltrepò, with the first located south of the pass and the second to the north. From the pass, the route proceeds towards Ruino, which was part of the lands of the Monastery of San Colombano during the Lombard period, then descends directly into the Val Tidone, right in line with the Molato Dam that forms Lake Trebecco.

The Molato Dam, built between 1921 and 1928, is located in that part of the province of Piacenza where the Val Tidone opens towards the Po Valley and acts as a barrier to the Tidone stream, creating the compensation reservoir known as Lake Trebecco, which has a usable volume of 8 million cubic meters of water.
