Colin’s report June 2025

We crossed from Crouesty to Trinite sur Mer in a F4 to F5. Being in the Quiberon bay means a short wave length as most of the bay is protected by land.

No one met us or answered on VHF 9 which was a shame. We took a decision to go on the hammer head which was already occupied by a small boat and we just fitted. We thought the small boat may get moved as it would fit in a catway but it did not happen.

The town is nice with some good shops and places to eat.

The market was OK but nothing special

Facilities in the Capitainerie were OK but there were better facilities with new washing machines around 400m further down the marina, towards the bridge.

The Petit Train was good and took us to the Carnac stones and alignments. It stops in 3 places but you can’t get off at the other 2 stops unless you pay again.

We met with the Harbourmaster who was very good and enthusiastic. This is a major sailing centre and they have some amazing yachts and events all year around. They are doing lots of development work at both ends of the marina and this will provide better fuelling, and allow them to accommodate more big boats in the future.

The boulangerie is currently closed and they hope to have one available in the town in the near future.

Update May 2025 – John Strudwick

  • All states of tide access
  • Loops on pontoon ends – no cleats
  • French water connectors (not English style) – bayonete type
  • Ordinary France showers – push button – The hot water wasn’t working when we were there (probably following the regatta). Was working a week later.
  • It does have laundry but the machines next to the Capitanerie are old and top loading. There are new facilities and laundry machines about 400m from the marina office.
  • Visitors ponton is the first one as you go in but still very full of race boats from last weekend’s big race – not many spaces. And it’s a big pontoon.
  • The secret is to arrive about 1045 when people are leaving.
  • Capitainerie is right at the end of the visitors pontoon.
  • Fish market next to Capitainerie
  • Restaurants are all along the front just beyond the Capitainerie – Brittania and Le Quai recommended
  • The little train is brilliant as it takes you up to the menhirs
  • Small carrefour set back from the sea front, five minutes walk.
  • Non-recyclable rubbish at the ends of the pontoons, bottles and emballage in car park.
  • 2 Uship chandlers – one at each end of the main strip. Quite a comprehensive stock.

Report July 2024 – Gavin May update

The river estuary seems to blend into the low lying land, especially in a bit of haze. Given the entrance is somewhat further in than you might imagine,  don’t miss your waypoint !

I think I am usually here early season when you can just grab a berth on the first pontoon past the breakwater, but in high season there was a lot of Vhf O9 calls asking for a berth so maybe make contact a few minutes out. Larger vessels seem before the breakwater.  The marina is of course in a river, so be on the alert for currents when berthing. Mid tide and there is quite a lot of shouting at times, hopefully not near you. The marina has some free bikes to borrow, suggestion is for a couple of hours.

La Trinite is certainly on the French sailing map, so make a double check that it is not hosting a large racing regatta. Easier said than done, I know!

Market days Tuesday and Friday.

Otherwise, I think all is as was, and if you have not been here, everything close at hand. I have always liked it here.

Gavin May report 2022

Everything is on hand in the pleasant street at the end of the pontoons, so this is an easy place to stop. Facilities have been refurbished since the last visit in 2019. A large visitors pontoon, but it is popular and busy, though the BdPort dories seem pretty active so I imagine will get you in somewhere. It is a feel-good kind of place to visit. Morbihan and Belle Ille close at hand, too.


We have not visited since 2016 because we found our 42’ motor cruiser was too long to berth on the visitor’s pontoon and usually, others have ‘bagged’ the few available hammerheads! On our last visit, we were allocated a semi-derelict pontoon about ½ mile north of the marina and the fuel pontoon. Although sheltered, the tide and river currents run strongly through the marina.

Ashore- and only 50m from the marina – are all the usual shops associated with a very ‘touristy’ but attractive small town. Whilst there are walks from the marina, many seem to involve much road walking. Incorporated into the same building as the Capitainerie, there is a particularly good daily fish market. We have found that the staff in the Capitainerie can sometimes be rather off-hand – as if we were a nuisance rather than we are their customer – but things may well have improved since we visited.

Maybe it was the fine weather, but something just feels right here.

Visitor’s berths are right in front of the HM and toilet block, fishmonger indoor stalls immediately behind, bakers off to the left, supermarket 150 metres to the right, and a pretty little market there too. Seems a bit more of a genuine town than next door, Crouesty. Just a few miles to the Gulf de Morbihan, Carnac town is well kept, those famous stones to visit…some good beaches towards Carnac coast. ..Put it on the list.

With thanks to Gavin May for the above report


Trinite sur Mer is a very large marina and is famous for some major international sailing races that start from there. It has all of the facilities expected of a large marina. The marina is located up a river and has good access.

Access is by a channel marked up to the port after leaving the Petit-Trého buoy to port. Respect the lateral marking of the river even at high tide, it runs along the large mudflat of Vaneresse which discovers widely from mid-low tide.

The visitor’s pontoon is the first on the left as you enter the port (pontoon D).
