Bubbling over ivory-white boulders, the steaming hot sulphurous waters of Saturnia, which run from Mount Amiata and the surrounding hills of Maremma, collect in the deep calcareous rock pools below. Popularised by the Romans, legend has it that the Roman god of Saturn first created the springs to pacify mankind. But, after a malaria outbreak, they were completely forgotten about until the 19th century. Today, thousands flock here in search of the teal-coloured curative waters and the sulphur-rich mud, renowned for lowering high-blood pressure, and treating various skin diseases. These thermal baths reach around 37°C, and are suited to every season. Although nearby Terme di Saturnia offers treatments, these wild springs are free.
