There are many natural thermal bath areas near Terra delle Sidhe, but one of the warmest is Petriolo about 45 minutes from the farm.

The local baths are free, and you can enjoy dipping in the different pools ranging from HOT to cool. You can always jump in the nearby river if you really want experience a more extreme hot-cold plunge.

There is also a rush of water pumped through pipe where you can stand below and let it cascade on your back and neck like natural waterfall massage.
