Port of Ploce is a port of the Central Adriatic Coast at the position of 43° 03' North latitude and 17° 26' East longitude. It is a very suitable natural harbour situated in a bay, three kilometers from the mouth of the river Neretva in the north-west direction. The bay is protected from the south and south-west by the peninsula of Peljesac which forms a natural breakwater for the port.

The port of Ploče has natural and geo traffic position, which enables a quality maritime connection both with the cities on the Adriatic Coast and in Italy and with the ports in the entire world, and is directly connected with its hinterland in Bosnia and Herzegovina and also with the Nort-East of Croatia, as well as with Central Europe by railway and by road (E-73), which stretches along the route of Corridor Vc (Budapest-Osijek-Sarajevo-Ploce) and turns tereby the port of Ploce into the sea port of this branch.

The port of Ploce is located next to the Adriatic Highway (E-65), the road that stretches from Trieste via Rijeka and Split to the extreme South point in this part of Europe. The remaining part of the modern motorway is currently being built (to be completed by End 2009) and will constitute the quickest connection between the port of Ploce and Zagreb. Special quality has been achieved by the opening of a weekly feeder line, which connects the port of Ploce to Malta and Gioa Tauro.

The international airports in Split and Dubrovnik (approximately 120 km away) and the airport in Mostar - BiH (60 km away), are located in the immediate vicinity of the port of Ploce.
