Beyond the park (in the opposite direction to the Tanaro) the trail becomes less obvious and continues narrowly along the river. A few meters more dangerous directly on the water and with sheer gullies, which do not leave much room to pass. Beyond it becomes wider again.

A cavity in the stone houses an altar and just above the statue of the Madonna. A silent, peaceful place, a few meters from the city center and traffic.
