The National Park of the Casentino Forests, Monte Falterona, Campigna, covers an area of about 36,000 ha, equally divided between Emilia Romagna and Tuscany, including the provinces of Forlì-Cesena, Arezzo, and Florence. It extends along the Tuscan-Romagna Apennine ridge, descending steeply along the parallel valleys of the Romagna side and more gradually in the Tuscan side, which presents itself with softer slopes, up to the wide valley bottom formed by the Arno. The Romagna side includes the territories of the municipalities of Bagno di Romagna, Santa Sofia, Premilcuore, Portico-San Benedetto and Tredozio. On the Tuscan side are the Casentino municipalities of Poppi, Bibbiena, Chiusi della Verna, Pratovecchio Stia and, finally, those of the Mugello villages of San Godenzo and Londa.
