The River Orcia runs south of San Quirico through a typically Tuscan landscape (the countryside presents a picture of undulating hillsides dotted with clumps of cypress trees). The via Francigena, used by pilgrims and merchants in the Middle Ages, passes through the valley. In the distance, you will be able to see small towns capped with mighty fortresses, such as Rocca d'Orcia or Castiglione d'Orcia, while the thermal station of the hamlet of Bagno Vignoni provides a relaxing interlude.
