Located in the picturesque Piennolo valley is the charming Fonte del Formale, a natural spring with an ancient history that could date back to the Roman era. Its name "Formale" derives from the inviting invitation to stop and taste its fresh water and is easily accessible via a pathway. The crystal-clear water that gushes forth flows into two communicating basins, while the surrounding rocky walls are dotted with plants such as pimpinella, heather, cyst, and thyme, painting a breathtaking picture in every season. The Fonte del Formale is not only a source of drinking water but also a hiking and relaxation destination in nature.
