Walks and hikes in the Gulf of Morbihan


The Gulf of Morbihan forms a small inland sea of 12 000 hectares sheltered from the swell.

A long time ago, when the rivers had already dug their beds, the waters of the Atlantic invaded the “Mor-Bihan”, “small sea” in Breton.

This is why the ocean ventures so far inland towards Vannes and Auray through rias with a typically Breton character. The gulf encloses the ancient hills in a real archipelago where the sea, the land and the sky mingle in changing and unusual landscapes.

You will fall under the charm of the Ile aux Moines and the Ile d’Arz, but also of its numerous rocky or wooded islets which sometimes have a fishermen’s hamlet or simply a flock of birds.

“Legend has it that there are as many islands in the Gulf as there are days in the year.”

To discover the bay, let yourself be taken on a trip in the Gulf of Morbihan or a stopover of a few hours on an island. Daily departures take place from Baden, Arradon, Vannes or Port-Navalo.

How about a weekend in a sea kayak to cruise from island to island and discover the bay at the slow rhythm of the paddle? You can easily rent a boat from the sailing schools located around the bay and even enjoy a guided kayak tour.
