Cornei Climb is the steep dirt road climbing to Orco from the Val Cornei: number 64 on the Finale Outdoor Region map, easy-to-intermediate cross-country.
It leads to Orco after the end of the Borderline trail, in an area also popular with climbers and hikers.
At certain times of year water leaves debris on it, but it stays rideable, although the climb has steep, slippery sections. Before you set off, check on the Finale Outdoor Region website that it is open: trails close for maintenance, races or bad weather.
