About 12 kilometres outside Chianciano, you’ll move back onto the Sentiero della Bonifica, which will take you to the Lake Montepulciano Nature Reserve and, shortly after, Lake Chiusi. Both the nature reserve and Lake Chiusi, home to herons and little egrets, are oases of silence and are rich in stories and legends. On the night of July 3rd, many people still gather at the lake to try to spot the golden trail left by St. Mustiola on the water. Legend says that the saint, persecuted and chased by Emperor Aurelian, managed to cross the still and dark waters of the lake at night by using her cloak as a boat, guided by the light of her trail.
Chiusi is located a few kilometres to the south, where we recommend a visit to the Labyrinth of Porsenna, named after the Etruscan king who dared to challenge the Romans, successfully defeating them.
The itinerary continues towards Monte Cetona, home to Etruscan secrets, overlooking many villages and vineyards and the hills in the Valdichiana and Val d'Orcia. After a few ups and downs along the SS 178, your next stops will be the villages of Sarteano (boasting dozens of well-preserved Etruscan tombs and frescoes) and Cetona (the Civic Museum of the Prehistory of Monte Cetona and the Belverde Archeological-Natural Park are worthy of any bucke tlist).
The final part of the route follows the SO 221, running along the slopes of Monte Cetona, and ends in San Casciano dei Bagni, a village in a magnificent location overlooking the fortress in Radicofani and the Val d’Orcia. You should also know that Casciano dei Bagni is a spa town, boasting an impressive 42 springs!
