There is still a lot to discover in Tuscany that is off the beaten track. One is Val di Chiana, with fabulous countryside and suggestive villages in a valley, and the best way to do this is to explore it along the Path of Reclamation, Il Sentiero della Bonifica. This last is a road opened a few years ago that crosses the entire valley along the Maestro della Chiana channel.
The ideal place to start this trip is undoubtedly at Chiusi, a small town with a prestigious history, having been among the most powerful of the Etruscan towns in the area, powerful enough to have threatened Rome with their king Porsenna in 508 B.C.E.
