The Natural Reserve “Cornate e Fosini” (www.riserva-cornate-fosini.com)is easily accessible on foot directly from the Town of Gerfalco. You can enjoy hikes or horseback rides on this area and experience the geological and naturalistic features of the reserve, such as the castle of Fosini (in Siena district) and the red cave on the Cornate (here was extracted the red material for the floor of the cathedral in Siena).
Many are the wild animals which populate the reserve: wildcats, martens, roe deers, fallow deers, porcupines, weasels and skunks. You can see various rare insects such as Carabus alysidotus, la Thecla betulae e la Maculinea arion.
