A short variant of the itinerary C. You start from Tiarno di Sotto, behind the church, and take the Via Alla Sega, that goes beside the sport centre. Before the bridge you take on the right a steep road in the direction of Croina's hay-lofts. You pass the wash-house, the aqueduct, the locality Castello (cross on the right) and the Roman Bridge. You reach, after some steep cemented slopes, another small bridge. You cross it and go up until a crossroad where you turn to the right and cycle on the asphalted road until Giumella Pass.
