Where is the Port de La Trinité-sur-Mer?

The Port de La Trinité-sur-Mer stretches along the west bank of the Rivière de Crac’h, alongside the town. The pontoons lie in the river between the Pont de Kerisper to the north and the Môle Tabarly at the southern end, in front of the waterfront road Cours des Quais with its cafés, restaurants and shops. The Capitainerie, the harbour office, is on the quays. South of the town, the river mouth opens out into Quiberon Bay at the Pointe de Kerbihan.

What is the weather like around the Port de La Trinité-sur-Mer for sailing?

On the Breton coast the wind most often blows from the west and southwest. Spells of north-easterly wind often bring sunny sailing days in summer, and on warm summer days a sea breeze sets in as well. Météo-France issues a strong wind warning for the coast as soon as wind of force 7 Beaufort or more is observed or expected.

The sailing area has pronounced tides. In the Gulf of Morbihan the tidal stream reaches up to 9 knots in places, and it also runs very strongly at the entrance near Port-Navalo. If you are here for the first time as crew: if your sailing trip heads into the Gulf, the departure time therefore depends on the current.

Which destinations are close to the Port de La Trinité-sur-Mer?

From the Port de La Trinité-sur-Mer you can reach the islands of Quiberon Bay, the harbours of the Rhuys peninsula and the Gulf of Morbihan in short hops. The distances are rounded figures over water on the usual course from the harbour; for precise planning, rely on the chart.

• Port-Haliguen near Quiberon: approx. 7 nm
• Port du Crouesty in Arzon: approx. 8 nm
• Entrance to the Gulf of Morbihan near Port-Navalo: approx. 6 nm, Île-aux-Moines in the Gulf approx. 10 nm
• Houat: approx. 12 nm
• Le Palais on Belle-Île: around 16 nm
• Hoëdic: approx. 16 nm

Belle-Île, Houat and Hoëdic

Le Palais, the main town of Belle-Île, lies on the island's northeast coast and is a full day's sail across the bay from La Trinité-sur-Mer. Houat and Hoëdic lie south-southeast of La Trinité-sur-Mer and east of Belle-Île; depending on the wind, you can combine both islands into a loop.

Port-Haliguen and the Port du Crouesty

Port-Haliguen lies on the east side of the Quiberon peninsula, south-southwest of La Trinité-sur-Mer, and is the shortest hop across the bay. On the east side of the bay, the Port du Crouesty lies at the tip of the Rhuys peninsula; you can find out more in our profile Port du Crouesty in Arzon.

Gulf of Morbihan

The Gulf of Morbihan is an inland sea with around 50 islands and islets covering 115 square kilometres. It is connected to the open sea only by a narrow channel about 900 metres wide between Port-Navalo and Locmariaquer. Because the current runs very strongly there, you should plan your passage with the current running in your favour.

What can you do on a harbour day in La Trinité-sur-Mer?

You can reach the beaches, the coastal path and the market on foot from the harbour, so you don't need a car.

Coastal path to the Pointe de Kerbihan

The customs officers' path starts at the Capitainerie and leads south past the beaches of Men Allen, Kerbihan and Grazu to the Pointe de Kerbihan, with views across Quiberon Bay. The waymarked path is around 6 kilometres long and can be walked all year round. It continues to the beach of Kervillen and past the salt marshes, which were restored in 2012 and are considered the northernmost in Europe.

Kervillen beach and Stuhan island

Kervillen is the town's large sandy beach. At low water you can walk from the beach across a sandbank to the small island of Stuhan; keep an eye on the incoming tide.

Sailing history at the harbour

La Trinité-sur-Mer is closely linked to offshore sailing. This is where Éric Tabarly had the Pen Duick II built, in which he won the English transatlantic race in 1964. During major regattas such as the Spi Ouest-France and the Tour de Belle-Île, the harbour is especially busy.

Market and fish hall

There is a market on Tuesday and Friday mornings, and the fish hall at the harbour sells fresh fish every day.

Carnac stone rows

In the north of the municipality, the stone rows of Carnac begin with the menhirs of Petit Ménec. From there it continues to the great Alignements de Carnac. Almost 3,000 menhirs stand here in rows, erected between the 5th and 3rd millennium BC. Information, tickets and guided tours are available at the Maison des Mégalithes at Ménec, which is open daily except for a few public holidays.
