The itinerary starts from the Varzo historical town centre. We take the nice mule track which goes up along the left-hand-side of the river crossing Varzo up to the Colla area and then follow along the nice stone-paved mule track tract along the Crucis Way (Via Crucis, which dates to the second half of the seventeenth century) with some really important Chapels which take us up to Durogna. Some stations (namely numbers II, III, and V) have been destroyed in order to build the road which takes us to Colla. The Durogna Oratory (which dates back to the XVII century) homes some very nice frescos by Vigezzo painters (Borgnis and De Giorgis).

At Varzo, by the Park Offices a multimedia museum tells the archeological story of these valleys and in particular of the Mesolithic hunters which 8,000 years ago frequented the Veglia basin in order to hunt.
