An incredibly narrow valley between the ridge of the Reno Valley and the Lavino Valley. A road, Via Sant'Anna, runs along it all flanked by the Olivetta stream and the overhanging clayey walls. The stretch that I have indicated is what can be done with a road bike; beyond, further paths branch off that climb up along the hills towards the sources of the torrent. There is also a beautiful spring from which to drink the freshest water.
