The Public Natural Reserve Gola del Furlo, established in 2001, occupies a surface of about 3.600 hectares among woods, fields and pure summits, which includes the canyon of the Candigliano flow. It is located in the province of Pesaro-Urbino and included in the cities of Acqualagna, Cagli, Fermigliano, Fossombrone and Urbino. It is a real paradise across the Candigliano flow, which wanders among the majestic rocky sides of the canyon. Here the suggestion of the landscape combines with an extraordinary natural treasure proud of a unique example of flora and fauna.
