The Terme di Saturnia are a group of springs located in the municipality of Manciano, a few kilometers from the village of Saturnia. The springs that feed the baths, which are found in the south-eastern valley, cover a vast territory that stretches from Mount Amiata and the hills of Fiora and Albegna rivers to the Maremma grossetana at Roselle (Terme di Roselle) and Talamone (Terme dell'Osa).
One legend, according to the Etruscans and Romans, was that the Terme di Saturnia were formed by lightning bolts, thrown by Jupiter. During a violent quarrel between the two mythological deities, the bolts thrown towards Saturn had missed, causing the formations.
The sulphurous spring water, at a temperature of 37.5 °C, are well known for their therapeutic properties, offering relaxation and well being through immersion. The main thermal waterfalls are the Mill Falls, located at an old mill as well as the Waterfalls of Gorello.
The yield of the source is about 800 liters per second, which guarantees an optimal replacement of water. The chemical make-up is sulfur, carbon, sulfate, bicarbonate-alkaline, earth, with the presence of hydrogen sulfide gas and carbon dioxide. The minerals dissolved in water amount to 2.79 grams per liter.
The area of Saturnia Spa presents, as a whole, a large and freely accessible area where it has developed the famed luxury spa of Terme di Saturnia, where, in addition to various thermal treatments, also produces thermal perfumes and creams for men and women.
