After Ponte Nuovo be careful not to follow the bend in the road but climb along the steep cobbled road towards San Gallo which turns into a mule track. Follow the mule track until you take the path next to the water mains (crossing the road to Briolo). Continue along the path which follows the road between San Gallo and Dossena until you reach the Church of San Gallo. Continue along the road which flanks the church towards Foppa until you reach a small chapel/shrine. From here the path which passes alongside Calecardi begins and in a little over half an hour will take you to Trinità di Dossena.
