This loop itinerary around the Cecina River takes us on a discovery of the history of the area.

Along the way we stop to visit the Archeological Museum set up inside the 18th-century Villa Guerrazzi. The Museum traces the history of the valley in a sort of journey from the Paleolithic age to the Roman age, with a special focus on the Etruscan people. Inside the Villa we can also visit the Museo della Vita e del Lavoro, which collects the tools of peasant work in the northern Maremma.

A must-see is the Archeological Park of the Roman villa of San Vincenzino, a Roman building built from the second half of the first century B.C. on the model of the urban villa. Particularly striking is a visit to the large subterranean cistern, which is entirely accessible.

Viewpoints along the banks make for a very pleasant tour, especially at sunset.
