The hot springs of Petriolo are located halfway between Siena and Grosseto. The waters are around 42°C (107 F) warm and give way to a great experience, especially during winter: just imagine the contrast between the hot water and the cold air outside.

Fun fact: the pools are located right below the ruins of fortified thermal baths dating back to the Roman era. At this point, we can take for granted that Romans really loved hot baths… easy to understand the reason why, isn’t it?
