This itinerary connects the four villages of the Dianese Valley, through ancient historical pathways and mule tracks. It is a circular track, and can be followed beginning from each of the mentioned villages, without necessarily starting by the order here proposed.Starting from Diano Borganzo, a hamlet of Diano San Pietro, you follow the ancient mule track, indicated as Via Borello, from the Oratory - with its elegant decorated façade - until the St. Pietro river, where you will reconnect to a cemented street unwinding among numerous private houses. You walk on the slope, beyond a curve on your right, and you come again on a mule track at your left that will bring you to Diano Borello, across terraces and olives. Once in Diano Borello, you go ahead on a cemented mule track with some stairs, beside the back of the church. The church, in front of a tiny and beautiful parvis, hosts a nice polyptych, painted by Antonio Brea in 1516. You walk on the slope among the houses until you reach the street Provinciale for Diano Arentino, with a wide curve on your left. Following the Provinciale Street, you reach the hamlet of Borgata Bonifacio and then further on, you enter the olive terraces. The farther you walk far from the village, the more you will notice how olive terraces have been abandoned. Terraces are sometimes invaded by the bushes and trees of the Mediterranean vegetation (especially broom, mastic trees, myrtle, cistus, and strawberry-trees and durmasts).
The mule track steeply descends on your right, to the Chapel of St. Mauro, immediately after the Provinciale Street, and goes ahead among the houses, until the hamlet of Diano Borello, Borgata Virgilii. You walk beyond the greenhouses and descend along the dirt road right before the bridge. You cross the exposed gravelly bed of the Evigno river where you can admire the ancient medieval bridge named “della Madonnetta”, for the presence of a votive aedicule. You follow the slope on your right, to the houses of Diano Roncagli.
Walking along the narrow streets among the houses, called in Ligurian dialect “carruggi”, you reach the church, at the top of the village, and then beyond, on your left, you walk on a steep mule track among olive terraces. After having crossed a little group of houses upon Roncagli, you go northernly on the ridge. The caselle are little stone buildings, used as a shelter, or as storage. Today, the growth of spontaneous vegetation, is so thick, that it’s nearly impossible to pass through these lands, unless you follow the pathway. You will then reach the watershed in the Torracchetta locality, along a votive pillar.
The vegetation is typical of the Mediterranean vegetation, and often dominated by durmasts. You go up on your left, to the ridge, beyond a stone “casella”, and, about 10 mt. before another casella, close to the top, you leave the mule track and you descend on your right, following a pathway that goes along ancient terraces, until another casella, in a plain area, on the north eastern side of the hillside, about 20 mt. from the watershed. This area, continues today as a pasture.
Further on, you go past two ditches, along on the lines of fracture of the limestone. Geologically, this limestone is part of a local land formation denominated “Flysch with Helmintoids”. In the vicinity of a big casella, the pathway comes to a bright street that leads to a zone which has been recently colonized by tourists and residents: we find many houses, new and restored, with attractive greenery. You enter the street that leads to the locality “Le Villette”, you continue on the pathway, and, beyond the votive pillar, you descend the ridge among the olive trees, to the hamlet of Camporondo. Walking in the streets, you can admire picturesque scenes, with houses close to one another and the narrow lanes. At the bottom, descending on the left, you reach again the Provinciale Street, by a hairpin bend before the curve, where there’s the oratory of Diano Borganzo, the beginning of this itinerary.
