The Gulf of Morbihan is one of the leading destinations in the south of Brittany. 20 km long and 15 km wide, dotted with islands (30 to 40) and islets, it opens on the Atlantic Ocean by a narrow neck between Locmariaquer and Arzon. At the mercy of the tides (caution, there are very strong currents), the landscapes change.
Vannes is the capital of the Gulf (and former capital of the Dukes of Brittany). From a historical point of view, this is probably the most interesting city. The seaside resort is located on the peninsula of Conleau.
Locmariaquer and Arzon are the gateways to the Gulf of Morbihan. Both have the advantage of having a coast open to the Gulf and an offer on the Atlantic Ocean, ideal for swimming (ocean beaches are much nicer).
Auray is also a must-see for the beauty of its heritage. There are beautiful timbered houses, imposing stone buildings, a bridge to cross from one side of the city to the other and many restaurants right on the harbour.
The two main islands of the Gulf are the Island of the monks and the Island of Arz. Both can be visited (boat access).
There are many beaches in the Gulf of Morbihan. However, one must enquire before having a swim because the currents are very strong. In general, it is safer to swim in the ocean.
In the vicinity, there are also numerous beaches in Brittany around the peninsula of Quiberon.
