The route begins from the ancient thermal springs called the “caldane” and touches upon some of the principle springs of the River Elsa. Along the route it’s possible to see a few sections of the ancient Via Francigena which was an important trade road that connected Rome with northern Europe. Along the course of the river you’ll see an antique mill and the Diborrato waterfalls . The trail along the Elsa will show you the typical river vegetation.
Other places not to miss are the Grotta dell'Orso, the Conchina, the Masso Bianco, the Nicchia and the Spianata dei Falchi, each with its own particularities. This natural richness has been recognized with the institution of a protected area in the River Park of the Upper Val d'Elsa which includes the town of Colle Val d'Elsa and streaches from Ponte Santa Giulia to Ponte di Spugna including the Caldane thermal springs which were known to the Etruscans and Romans.
