Val di Merse is located in the western edge of Siena and in the southern border of Val d'Elsa, between the rivers Farma and Merse (from which it takes its name as well). It is famous for its beautiful landscapes, its unspoilt nature and the healing powers of the many waters of Val di Merse.
Some of the villages in this area that are definitely worth a visit are Monticiano, Chiusdino, Murlo and Sovicille, such small villages that you will have the opportunity to visit at least a couple of them on the same day.
If you look between the woods of Val di Merse you will also find a numerous amount of medieval hamlets and castels hiding between the trees.
