About the harbour
Automatically summarised text: Automatically summarisedfrom the harbour's website · 28 September 2026Port Cergy is a river marina in the Paris region, situated on the Oise at PK 9 between the lock at Pontoise and the confluence at Conflans-Sainte-Honorine. The marina has 60 berths for boats from 5 to 22 metres, offering modern facilities combined with the charm of the river setting, suitable for short stays as well as long-term rental or winter storage.
The harbour office welcomes boaters seven days a week during the season and is accessible around the clock, helping with information, mail and tourist advice. Sheltered pontoons are reserved for marina users. Payment can be made by card, cheque or cash.
The marina offers washrooms with hot showers, toilets and a laundry, as well as a slipway for launching. Water, electricity and free internet access are available at the berths, along with a pump-out station for wastewater and free parking.
Step ashore to explore the old town of Pontoise with its shops, restaurants and a museum, as well as Pontoise Cathedral. There is also a leisure park nearby. Tie up at the sheltered pontoons of Port Cergy and take a short walk into the old town of Pontoise.
