Locmariaquer, oyster capital

Locmariaquer, a commune in the Golfe du Morbihan, is one of the great capitals of Breton oyster farming. Its oyster beds, nourished by the rich waters of the gulf, produce flat and hollow oysters renowned for their delicacy and iodized taste. It is this age-old tradition that the Oyster Festival honors each year, attracting thousands of seafood lovers to this village with its rich megalithic heritage.

The oyster opening competition

A highlight of the festival, the oyster opening competition pits amateurs and professionals against each other in a friendly but serious contest. Participants compete to open a dozen oysters as quickly and cleanly as possible, cheered on by the public. This competition, which has existed for over 25 years, perpetuates the tradition of local oyster farmers and highlights a technical skill that is an art in itself.

Tastings and meal platters

The festival offers visitors the opportunity to taste freshly opened oysters, accompanied by white wine, as well as meal platters including oysters, seafood, far breton, and other local specialties. The catering stands, run by the Festival Committee and the Oyster Farmers' Syndicate, offer fresh, quality products at affordable prices.

Entertainment and festivities

Beyond gastronomy, the Oyster Festival offers musical entertainment, shows for the whole family, boat trips in the gulf, and visits to the oyster beds. The atmosphere is that of a large popular and maritime festival, where visitors enjoy the exceptional setting of Locmariaquer and the view of the Golfe du Morbihan.

Exceptional megalithic heritage

A visit to Locmariaquer for the Oyster Festival also allows you to discover the commune's remarkable megalithic heritage: the Grand Menhir brisé d'Er Grah, the largest known menhir in the world, the Table des Marchands, and the tumulus d'Er Grah, witnesses to a fascinating prehistoric civilization.
