The route starts in the municipality of Gravedona ed Uniti, from the car park on via San Gusmeo, not far from Palazzo Gallio. You start uphill on a paved road that leads to Dosso del Liro, passing through the Negrana area from the S.P. 4. In some sections the road is very steep, the use of an electric bicycle (e-bike) is recommended. Once you reach Dosso del Liro, continue by following Via dei Monti Lariani, a trail that develops along the coast. The stretch offers a series of ups and downs that cross the mountain. The route is characterized by breathtaking views. You reach the Ronzone stream where you need to cross a bridge on foot, holding the bike by hand. After the bridge, continue by following the stairs to a signpost. From this point, continue with a short succession of climbs and descents. Then you arrive at a forest road that leads to the Church of the Madonna del Gorghiglio in the village of Peglio. From Peglio, you start a climb on a paved road that leads to the Church of Santa Croce di Naro and, along beautiful well-maintained mule tracks, you descend. It is necessary to pay attention to driving for the marked slopes. The route ends with the return to Gravedona ed Uniti. This route offers a complete cycling experience, with challenges both uphill and downhill, as well as stunning views. It is possible to refuel with water at several points. The ascent in an e-bike is recommended, without the assistance of the engine this route can be extremely challenging in the steepest sections.
