Established in Roman times, the sulphuric waters   in Saturnia rise at a temperature of 37.5°. Famous  for their therapeutic properties, simply sitting in them brings a feeling of relaxation and well-being. The surrounding nature is also noteworthy with the pungency often associated with the Tuscan Maremma, especially during the summer, with colours that range through all imaginable shades from a dull green to bright yellow trhrough to a  brown sometimes so dark it is practically black.   

The Cascate del Mulino are one of the most impressive of the hot spring waterfalls, named after the old mill they powered  another being  the Cascate del Gorello.

Saurnia's hot springs lay behind the success of  a thriving tourist complex, built around the spring waters that rise just a few kilometres away in the valley to the south west of  Saturnia in the commune of Manciano.
