The “Pozzo Sfondato”, a Jurassic well on the volcanic rocks of the Evola River; a wild place where the river flowing over the rocks forms small waterfalls. Here over time, the water has dug into the rock some real wells or holes where the people of Montaione (and not only) come to cool off on hot summer days. The spot is easily accessible thanks to a dense network of nature trails in the Municipality of Montaione. Near the area you can still see the ruins of the old Molinuzzo delle Pozzole, but above all an old brick bridge that, in addition to the passage of goods, animals and people, was used to cross the "millstone" of the Molino delle Pozzole, located at valley at a distance of about 300 meters. A wonderful and unique place: nature that is combined with history, where it is possible to understand a glimpse of the local economy of the time thanks to the numerous mills along the river. A magical place for those who love bathing rivers and trekking itineraries.
