About 40 minutes south of Siena and a bit over an hour from the Tuscan coast, Val d'Orcia lies to the east of the Maremma and to the west of Montepulciano and Umbria. The UNESCO world heritage site is made up by the territories of Montalcino, San Quirico d'Orcia (with historic spa town Bagno Vignoni ) , Pienza, Castiglione d'Orcia and Radicofani. The Orcia river crosses two more municipalities (Castel del Piano and my hometown Cinigiano ), where it divides the province of Siena from the province of Grosseto (Tuscany's two southernmost areas) before flowing into the Ombrone river.
