This track begins from Forcella di Olino and reaches the Culmine di S. Pietro, it’s a classic both for gravel bikes and e-MTBs. It also connects to many other tracks, and even reaches the Piani di Artavaggio. The itinerary is practicable in both directions, follows the entire agro-forestry-pastoral path and does not present any particular difficulties, so it's ideal for e-MTBs and for those who are less experienced. The route is all at high altitude, offering breathtaking views of Resegone, Valsassina and Val Brembana.

For a half-day itinerary you can to start from Maggio, reach Ballabio, take the road SP63 to Morterone up to Bocchetta di Olino and go down until the beginning of the agro-forestry-pastoral path. After the descent near the Culmine di S. Pietro, take the direction for Old Road to Maggio, inside a beech tree forest, that leads to source of San Lorenzo (Maggio). Here the ring ends. There are some rocky parts, not to be underestimated.
