Parco Termale di Terme di Saturnia

"A Soak in History The Maremma region of southern Tuscany, about an hour south of Siena, is an area of olive groves, wooded valleys, and ancient legends. One such tale, dating from the days of the Etruscans and Romans, chronicles an epic battle in which Jupiter threw lightning bolts at Saturn—and missed. As the story goes, when the bolts landed on the ground, they formed the bubbling hot springs now known as the Terme di Saturnia. Full of therapeutic minerals, the hot springs feed a variety of pools throughout the valley that have warmed and healed centuries of bathers. Today, you can soak up the goodness at the luxury Terme di Saturnia Hotel & Spa, which offers therapies performed with the waters, or at a free public bathing spot. To find the main one, head down a dirt path just outside of town, past a parking lot and changing area, until you spy a waterfall feeding a series of natural pools, each turned white by the mineral-rich water."
