The route starts from the small church of San Martino in the municipality of Abbadia Lariana, although the section from Lecco will soon be restored. After passing the towns of Mandello del Lario and Lierna and arriving near the cemetery in Varenna, the original route climbs towards the Val d’Esino: a gorge crossed by the stream of the same name and dominated by Mount San Defendente. A steep climb leads to the small and characteristic village of Vezio, in the municipality of Perledo, where a visit to its famous castle is a must. Continuing to climb through the woods and past Mount Fopp, you reach the village of Ortanella: a small hamlet immersed in the green of the mountains in the municipality of Esino Lario. Following the vehicle road through the meadows of Ortanella you arrive at the center of the village, known by the pseudonym of “pearl of the Grigne”.
The original route is now flanked by a less strenuous variant that runs along the lake: once you reach the village of Vezio you can cross part of the municipality of Perledo and its characteristic hamlets: Regolo, Gittana and Cestaglia, and then continue until you reach the municipality of Bellano. From the square of Vezio you descend towards the River Esino, which is crossed by the characteristic stone bridge and, leaving the old mill on the right, you go up towards the industrial area of Campallo. From here, taking the road for Regolo, you will come across a small church belonging to the list of Marian Sanctuaries and once you have arrived in the center of the hamlet, continue along the road that leads to the hamlet of Gittana. When you reach the Maglia chapel, take the paved road again and descend onto a mule track and, leaving the splendid parish church on the right, cross the historic center of Gittana. Climb once more, crossing a small wooden bridge over the Masna stream and, having passed the hamlet of Cestaglia, gradually go back down towards Bellano.
