Terme di Saturnia is one of the largest free spas in all of Tuscany and is located near Pitigliano, in the province of Grosseto. It is always a pleasure to come here to relax by soaking in the ever-warm water, in the evocative limestone pools with the clearest waters. The most striking point of these spas are the Cascate del Mulino waterfalls, which can be visited all year round.
