Pian Marino–Cia links the southern and northern parts of the Feglino area: number 391 on the Finale Outdoor Region map, easy all-mountain.
It is a handy transfer, partly on dirt road and partly on singletrack, with a few short climbs.
It crosses busy trails: watch out for riders on them. Before you set off, check on the Finale Outdoor Region website that it is open: trails close for maintenance, races or bad weather.
