From Monte Poieto, descend northwards and in a short time you will reach the gorge at Aviatico. The trail continues on the flat, always heading north, and soon reaches Cà Donadoni. At the fork, turn left and the path continues uphill to Forcellino, climbing along the ridge and coming out on a small hill where the Al di Mafé hut is located on the left.
It continues along a grassy ridge until it reaches the top of the mountain, then descends to a second col and, following the ridge, which is rocky in places, reaches the summit from where there is a beautiful 360° panorama.
The descent (northwards) is steep but without too much difficulty; the path soon reaches the wonderful roccolo di Barbata (junction with path no. 525).
Take the right-hand path that leads to the pleasant and austere village of Sedernél, where it joins path no. 527.
An alternative to the route described above is represented by the two paths starting from Costa Serina: the first starts at the Madonna della Neve Sanctuary, passes by the Aral stable and through a beautiful wood reaches the summit of Monte Suchello; the second starts at the Valle del Ferro and climbs to the Barbata brook following the Val Chignoli.
