Leave the motorway (Autostrada A12) at SARZANA. Just after the motorway exit turn right and at the first roundabout take the third exit, direction LERICI. Just after crossing the bridge on the river Magra turn right again following signs for Lerici. You will cross the village of Romito Magra, at the roundabout take the first exit following once again signs for LERICI (shortly after you will see a small COOP supermarket on your right). Follow directions to LERICI until the third roundabout (overall since leaving the motorway) where you take the second exit direction to MONTEMARCELLO. At the IP petrol station take the road up to the left towards MONTEMARCELLO. Continue up the road driving through the village of La Serra and until you reach the sign signaling the beginning of Zanego. Just after the white sign and a slight bend to the left you will see a paved road (with a sign saying "Pian della Chiesa" and several "No access" - "Strada Privata" signs) going uphill on the left-hand side. Take this road until you get to a Y junction (with bins!) where you should turn right following signs for Pian della Chiesa. Continue on the dirt track until you reach a crossroads where you should bear left again following for Azienda Agricola Pian della Chiesa. After about 200m you will see a dark green gate on your left signposted Az. Agr. Pian della Chiesa. This is the entrance to Pian della Chiesa. Once you go through the gate after a few meters take the dirt road on your left, drive through and park under the oak tree.
