This mountain bike loop takes you through the majestic mountain landscapes of the Upper Lake Como, up to Passo San Jorio, located on the border between Italy and Switzerland. The route passes three alpine refuges, Rifugio Mottafoiada, Rifugio Il Giovo and Rifugio San Jorio. The climb to Rifugio Giovo, a fundamental stop before tackling the final pass, follows the traditional route from the village of Garzeno. However, it is also possible to climb from Stazzona to create a loop that surrounds the majestic peaks of Monte Cortafon and Motto di Paraone, with a start and finish in the same municipality, which can be reached from the S.P. 5 from the municipality of Dongo on the lakeshore. The route winds its way mainly on asphalt roads and dirt roads, some of which have a compact surface and others with a more uneven surface. The climb to Passo San Jorio is a very exciting experience. You start from the square in front of the church in Stazzona, reachable by car from Dongo, you pedal uphill towards Cragno and subsequently, on dirt sections, you reach the panoramic Bocchetta di Sant'Anna and the suggestive locality of Monte Sassello to then reach Rifugio Il Giovo, located at an altitude of about 1,710 meters. The stretch becomes even more challenging up to Rifugio Sant'Jorio, located at an altitude of about 1,980 meters. During the descent back to Stazzona, you need to pay attention to the steepest sections along the historic military mule track; from Rifugio Il Giovo to descend, there are alternating more uneven terrain and more flowing sections on paved road. Along the route it is possible to refill water even if the fountains are only located in the first part of the itinerary. The climb in an e-bike is recommended, without the assistance of the engine this route
