What to do in the Gulf of Morbihan

The Île aux Moines, the Île d’Arz, the Gavrinis cairn, Port-Navalo, Locmariaquer, Vannes and Suscinio: the guide to visiting the Gulf of Morbihan, its islands and its shores.

7 min read

The Gulf of Morbihan is a small inland sea, opening onto the ocean through a narrow channel between Locmariaquer and Port-Navalo. It has around forty islands, only two of which are municipalities: the Île aux Moines and the Île d’Arz.

The Île aux Moines and the Île d’Arz

The Île aux Moines is a few minutes by boat from Port-Blanc, in Baden. Its paths lead to flower filled houses, beaches and a stone circle. The wilder Île d’Arz is reached from Conleau, near Vannes. Both can be explored on foot or by bike.

The Gavrinis cairn

On its islet, reached from Larmor-Baden, this stone tomb holds one of the finest engraved decorations of prehistory: almost every slab in the passage is carved. Visits are guided, with booking, in the summer season.

Gavrinis is part of the megaliths of Carnac and the shores of Morbihan, UNESCO World Heritage listed in July 2025, as is the Locmariaquer site and its great broken menhir.

The shores of the Gulf

Vannes, Auray and Suscinio

At the far end of the Gulf, Vannes has its ramparts and harbour. Auray keeps the harbour of Saint-Goustan and its half timbered houses. On the Rhuys peninsula, the Château de Suscinio, the summer residence of the Dukes of Brittany, rises on the edge of the marshes.

Towns and castles

The Gulf by boat

The simplest option is a cruise from Vannes, Port-Navalo or Locmariaquer, with a stop on an island. Kayaking and sailing are also possible, but the currents in the channel are among the strongest in Europe: go with an instructor.
