Take Strada Mulattieri and go straight ahead until it intersects with Strada Pozzetta to enter the valley at the foot of Moncalvo and Grazzano Badoglio. This area, considered the heart of Monferrato, is closely linked to land cultivation. In fact, you will find several farmhouses. Here people mostly work in the vineyards, which are very important for the local economy.
Keep going for about 1 km, pass through the fields again until you come to an intersection. Turn left into Strada Roncarino and go straight ahead for 2 km and a half into the fields. You get to the valley of Grana river, a small waterway that is tributary of Po river on the right side and almost entirely flows across the Province of Alessandria in the northern Monferrato. This river rises in the province of Asti, in Grana, from which it takes its name, as a result of a union of the two small rivers of Calliano and Grazzano Badoglio. The route continues along Strada Provinciale 38, then Strada Provinciale 29, until reaching the historic centre of Grana Monferrato.
