General Information about Gulf of Morbihan – Bay of Quiberon

This bay, located in Brittany, France, is made up of two complementary areas with an equivalent surface area (approx. 120 km²).

The Golfe du Morbihan (“Mor-bihan” means “little sea” in Breton) corresponds to a coastal depression, linked to the ocean by a narrow channel (0.9 km) and dotted with many islands. With every tide, approximately 400 million m3 of seawater pour in and out of the gulf creating strong currents on a flat bottom, contributing to the creation of a maritime ecosystem of great biodiversity.

Quiberon Bay, looking onto the ocean, is protected by a long peninsula linked to the mainland by a tombolo (buildup of sand). This mosaic of terrestrial and marine environments is faced with a double challenge: the control of urbanization, the management of tourist and leisure activities.

Située en Bretagne, cette baie comprend deux zones complémentaires avec une surface équivalente d’approximativement 120 km².

Le Golfe du Morbihan (“Mor-bihan” = “petite mer” en breton) est une dépression côtière liée à l’océan par un étroit canal de 900 m de large et jalonnée d’îles. À chaque marée, 400 million de m³ d’eau de la mer rentrent et sortent du golfe, créant des courants forts sur son fond plat, contribuant à la création d’un écosystème maritime de grande biodiversité.

La baie de Quiberon, face à l’océan, est protégée par une longe péninsule liée au continent par un tombolo (un cordon de sédiments ou sable). Ce mosaïque d’environnements terrestres et maritimes fait face à un double challenge: le contrôle de l’urbanisation et la gestion des activités touristiques et de plaisir.
