Petriolo Hot Springs are among the most beautiful and well-known spas in Tuscany. In this guide we will talk about the treatments, the prices of the resort and what to do in the surroundings of Petriolo.

Petriolo Hot Springs are, together with the Terme di Saturnia, among the most beautiful and well-known thermal spas in Tuscany.

Unlike Saturnia, the Petriolo Hot Springs remained “wild” for much longer, in fact, the spa dates back to the early 2000s.

The Terme di Petriolo, also called Bagni di Petriolo, are located in the hills of the Ombrone Valley, along the course of the Farma river, which flows between the provinces of Siena and Grosseto.

The history of the Terme di Petriolo begins in Etruscan and Roman times, when the locality was already known and mentioned in a prayer by Cicero.

During the Renaissance, they were frequented by important families of the time, such as the Medici and the Gonzagas and, apparently, the Pope himself.

The water of the Petriolo spas gushes out at 43 °, is particularly rich in salts and its properties have remained unchanged over the millennia. Characteristic that unites it to Saturnia is the strong smell of sulfur, due to the large concentration of hydrogen sulphide.
