Sea wealth

Mussel culture, or « culture and raising of mussels », a strong tradition

On the major part of the shore, we can see while the sea is low tide, surprising piling of stakes, regularly spaced: they are “bouchots à moules”, implanted since the end of the 19th century and they produce shellfish renowned for their qualities. It is the wealth of pure and well oxygenated waters of “la Vilaine” precisely that makes the quality of Pénestin’s mussels. Mussel culture is the most important economic primary activity of Pénestin.

The Port of Tréhiguier, a spot full of charm
