Bari to Igoumenitsa ferry info
Take a local train (1 euro) to Modugno, from the train station walk to the north Via Sigismondo (check map), cross the SS96 slightly to the right to Via Palese. Turn left when it joins SP 54, there will be a junction - walk carefully under 2 bridges untill you reach a roundabout. On your left/back you'll see two warehouses - there is a road between them leading to a gas station. It is guarded by a really high fence and dogs, but you might be lucky to meet someone from the service to open the gate for you.
