Antirrio is situated at the western entrance of the Gulf of Corinth. It is 3 km northwest of Rio, 10 km north of Patras and 9 km southwest of Naupactus. 8 km to the northwest is the 1,039 m high mountain Klokova[4] (also known as Paliovouna), rising steeply from the Gulf of Patras coast. The Rio–Antirrio bridge, carrying Motorway 5, connects it with the Peloponnese peninsula. Greek National Road 5 connects it with Missolonghi and northwestern Greece, Greek National Road 48 with Naupactus and Livadeia.
The Port of Antirrio is served by ferries that carry traffic between the Peloponnese and northwestern Greece. Its significance has decreased since the opening of the Rio-Antirrio bridge in 2004. It is still in use as a ferry port for hazardous cargo and by users attracted by the scenic route or the lower fare for crossing the Rio-Antirrio strait. Adjacent to the port there is a lighthouse and the fortress of Antirrio.
On the eastern pier of Antirrio port there is the Antirrio RTS (Regional Traffic Service)[5] which is part of the national Vessel traffic service system of Greece (Officially called Vessel Traffic Management and Information System). The RTS of Antirrio includes a building with the necessary electronics/communication equipment and a sensors/radar mast of 20m height. On top of the mast there is a remotely controlled CCTV camera, VHF antennas and the antenna of the coastal surveillance and navigation radar GEM RT02-25D.[6]
