Report July 2025
This is one of the most organised and well-run marinas we have visited for some time with an excellent Harbour Master, Tiphenn Le Bitoux, She is very organised, extremely helpful and speaks fluent English.
The marina is worth a visit and she will take bookings and will be as helpful as possible, especially with the Brexit paperwork.
The journey from La Corne to the marina takes a good 40 mins, so please allow enough time. The following video was taken at Low Water of approx 1.7m. It has been sped up in most places by up to 6x normal speed for your convenience.
Treguier is a very pretty town, up the lovely river River Jaudy and 5nm from La Corne lighthouse. Always arrive at slack tide which is near high or low water. It has a deep water harbour with a channel dredged to 2m. Speed limits are 5 knots in the channel and 3 knots in the harbour. 310 berths with 70 for visitors. Visitors berths are at the end of the first 3 pontoons on arrival (E, D and C). Max length is 12m with a few moorings for longer boats. A new pontoon has been added to the end of “E” for bigger and heavier boats and is called Pontoon F.

Pilot guide :
Some advice at very low tides
- There is a shallow point near red buoy N° 12, its deeper toward the commercial harbour dock
- When motoring toward the pontoons, stay near green buoys N° 13,15,17, it’s deeper
The speed limit below La Corne (marked on the light) is 5 knots, although not many local boats stick to this.



Only moor here on slack water. It is best to arrive half an hour before high tide. A strong current flows through the pontoons at a slight angle and there have been many accidents. Also use lots of ropes, springs and fenders.
Arrival (message from Port de Plaisance brochure) On arrival in high season wait near the end of the first pontoon (E) for the berthing master’s boat will welcome you and guide you to your berth, which is governed by the tide and current. Contact the harbourmaster in advance on VHF channel 9. During spring tides, beware of the very strong current in the marina, always berth facing the current. We advise against leaving at half tide. Follow the advice of the harbour master.
Speedbird advice “Take care with these type of river marinas as the tides run very fast, 9 knots or more at times so it is very hard if not impossible to moor a boat at any other time than slack water unless you wish to do some serious damage. There is a waiting pontoon North of the “marina” which is useful. When moored you will see the speed of the tide running past and even sometimes can read it on the boats log. Before departing take a look at the outdrives to ensure that no logs have got lodged around the stern, it is amazing what comes down (or up) the river.”
Normally we would suggest mooring on Pontoon E on the Northside, however, in our motorboat with the bow to the North, it was very noisy at night when the tide was coming in. It was a big spring tide and the wind was north and the chop made a lot of noise against the chines of the boat (maybe OK in a yacht). Mooring on the Southside of the pontoon may reduce the noise, some of the tide and some of the debris.

The facilities are good. Showers are free and included in the price. You have to pull a chain to make the shower work, which is a pain, especially as it only keeps going after you have let go of the chain for 5 secs in some showers and no seconds for others. For the loos, you have to press the button hard to make them flush.

The facilities, toilets and showers in the left of the angular buildings, capitainerie up the spiral stairs, bar on the right – all the essentials
Free wifi and coverage is fairly good, even at the end of Pontoon E. One code can do multiple devices which is much better than some other marinas where it is per device.
You can order croissants, pain au chocolat and a baguette from the marina office the evening before and they will be available soon after 07:00. Great service. Croissants are large.

A new supermarket opened on the entire ground floor of the Capitainerie building, where “Le Ponton” used to be. The BioCoop stocks everything and is so convenient for the visitors’ pontoon. It has fresh garlic to die for as well as good quality fresh produce and bread.
Pilot Guide
The route into Treguier is fine provided you do your research. The Grand Chanel is the easiest at all tides but does mean a longer journey for boats approaching from the East or North. There is a north channel but goes over a reef of rocks. The East channel looks fine but beware of 1.6m rocks etc at low water.
Once inside the channel, it is very well marked but you must ensure you keep the coloured buoys on the correct side. There is a green buoy after La Corne which looks too far East but is correct. The latest charts on our chart plotter seemed to be very accurate (Navionics) when we went through on a 0m tide! The last red buoy before the marina is quite close to the cliff. It is correct.
One of the last red buoys is the shallowest point (1m on a 0m tide). It is deeper towards the shore away from the buoy. There is a 2m channel dredged from the holding pontoon to Pontoon E.
If you leave around half tide going up, motorboats will have a good following tide all the way back to Guernsey.
Tourist Office
Treguier Tourist Office has moved and is now in the same building as the marina office. Very convenient.

The water connections are on the same post as the electricity and offer the female connection on must pontoons but on F pontoon, it is the screw fitting. For the french connector. you therefore, need a MALE connector to get water. There is no tap so the water is ON as soon as you plugin. Water pressure was pretty low and we needed nearly an hour to fill our water tank of 200 litres.
Market day
Market Day is on Wednesdays, guided visits in the city, festive Wednesdays at night with music and dances, classical music in summer and Saint Yves’ procession in May. The market is well worth seeing and one of the best quality markets we have seen (after Vannes and Etel)

Information
There is a Super U where you can hire a car but you need an International driving licence with a page in French. The marina office can advise ref other options.
Intermarche about 20 minutes walk from the marina. Useful as everything else seemed to close on Monday.
Harbour staff helpful and friendly.
As with most places in France, a lot of restaurants and shops are closed on Mondays. Probably the best day to plan to eat on board.
There is a marine shop just over the bridge. It has more than you think inside, especially clothes.
