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 Port of Antirrio is served by ferries that carry traffic between the Peloponnese and northwestern Greece.

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.

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.
