The Ferry of Rio is located north of the city of Patras and at a distance of 12 kilometres approximately. At Rio the Patras Port Authority only owns the wharfs and the electricity network. A port guard room is under the jurisdiction of the Port Police. Both the Eastern and Western Piers of the Rio Ferry area are under the jurisdiction of the Patras Port Authority. 

The frequency of use of the Eastern or Western Pier depends on the weather conditios and mainly on the wind direction.

At the Eastern Pier of Rio the portual area is 11.136 square metres. It includes wharfs which are 395 meters long and is lightened by 2 light pylons. At the Western Pier the portual area is 39.156 square metres including also a temporary pier of 18.205 square metres which was constructed for the needs of the construction of the Rio Bridge. The Western Pier includes wharfs which are 259 metres long and is lightened by 3 light pylons. 

The traffic of the Rio Ferry was greatly reduced after the start of functioning of the Rio Bridge. Nevertheless the low prices of the ferry with respect to the bridge toll remains an advantage for the Ferry traffic. The aim of the Patras Port Authority is the exploitation of the free portual area in cooperation with the local society.
