Tucked into the Tuscan countryside of the Maremma, the Cascate del Mulino take their name from an old mill standing beside their natural pools. For centuries, the sulphurous Gorello stream has carved the limestone into a cascading series of basins, a landscape shaped more by time than by human hands. Local legend even claims the springs were born from a bolt of Jupiter's lightning during a quarrel among the gods.
Insider tip — The Cascate del Mulino are free travertine pools open around the clock, tucked just below the paid resort. Come at dawn or after sunset to skip the midday crowds. The sulphurous 37 °C water has a distinctive egg-like smell — arrive early as the free parking fills up fast.
