From the splendid town of Amandola along secondary dirt roads, follow the eastern slope of the Sibillini Mountains maintaining an altitude of about a thousand meters above sea level towards the Infernaccio Gorges. From here a cart track leads to the paved road to Isola San Biagio, at the foot of Monte Sibilla, and then continues up to the passage over the river Aso and the woods that lead to the Montegallo area at the foot of the imposing Monte Vettore.
