Easy route mainly on dirt tracks serving the pipeline. Quite steep section of mule track between Premia and Cagiogno. 

From Verampio, following the directions of Orridi di Uriezzo, take the dirt track that first crosses Stream Devero with a ford and then gradually climbs. First reach Ponte di Maiesso with the beautiful potholes of the giant’s kettles into the white rock and continue on the track (do not cross the bridge) until you reach the entrance to the Orrido Sud, a deep rock incision equipped for visiting with metal ladders. After visiting the canyon, continue along the track to the Oratory of Santa Lucia where the road returns to being paved. Follow the steep road to Balmafredda, an imposing gorge carved into the rock equipped as a climbing site. At the crossroads, continue towards Premia until the road merges the Val Formazza state road. From the crossroad follow the main road for 150 meters downhill (watch out for traffic) and near a chapel (Cappella dal Self) take a steep mule track which descends until it crosses the River Toce and then climbs even steeper to the village of Cagiogno. This stretch is not very good for cycling. Alternatively, from Cappella dal Self it is possible to continue on the main road until Piedilago and  then to take the paved road to Cagiogno to avoid carrying the bike on your shoulder. Follow the asphalted road from Cagiogno until before the bridge over the Toce, then turn right following the arrows with G00 signpost, take a track that continues along the artificial lake of Piedilago. From the end of the lake, return to the paved road which continues passing downstream the village of Cristo along the river. Further the track runs beautifully through well-kept meadows until reaching a bridge in front of the Terme di Premia.
