A route rich in history and nature with a touch of adventure.
The Rio dei Molini valley between Grumes and Grauno has a concentration of at least 20 water-powered machines, including mills, sawmills and forges, with four restored factories and an exhibition room dedicated to water-related trades. The Sentiero dei Vecchi Mestieri (Old Trades Trail) connects these buildings, bringing unforgettable impressions to the visitor.
