It is located on the inner part of the Bay of Thermaicos, on the northern section of the Eastern Mediterranean Sea, to the west of the center of the city of Thessaloniki. Approach of the ships is accomplished through a natural channel of substantial depth, not needing thus any further deepening.
It occupies a total space of 1.5 million square meters and it spreads across a length of 3.5km.
The installations include 6 piers spreading on a 6200 meter-long quay and a sea depth down to 12 meters, with open and indoors storage areas spreading on a total of 600,000 square meters, suitable for servicing all types of cargo as well as passenger traffic.
The port also has installations suitable for liquid fuel storage and it is located in proximity to the international, natural-gas pipeline.
