From Porta Cappuccini, a dirt road on the left runs along the medieval walls. Continue uphill until you reach a picnic area, and then go downhill to Eremo delle Carceri, follow Fosso delle Carceri upstream and reach Croce di Sasso Piano.
At the top, you will find the dolines of Mortaro Grande and Mortaiolo.
Go downhill to Fonte Bregno, go ahead among Downy Oaks and Maple Trees, and then among Olive Trees. Here you will enjoy a beautiful view of Spello.
The trail ends at Fonte Bulgarella.
