Why to visit Bagni San Filippo?
Those natural hot springs are just 30 minutes away from Montepulciano (medieval town). They are located in southern Tuscany
They are easily reachable with car... the parking above springs is still free which is pretty odd for Italy. Then you'll have to hike about 5 minutes to get down in a beautiful valley where u'll find this natural springs...
U can find pools from 20°C and up to 35°C...
And the best of it... they are still free :)
