Visiting Vannes means stepping into a walled town built like an amphitheatre at the head of the Gulf of Morbihan: ramparts and formal gardens, old wash-houses by the water, half-timbered houses around Saint-Pierre cathedral, then the marina opening onto the gulf and its islands. This Vannes travel guide covers what to do in one or two days, which places to reach next and which season to choose, using Météo-France climate data.
The figure to remember: the Vannes-Séné weather station records an average of 1,981 hours of sunshine a year, against 1,717 at Paris-Montsouris, or about 0.7 hours more per day (Destination de Voyage calculation based on Météo-France). Southern Brittany is not as grey as its reputation: it rains more than in Paris in autumn and winter, but summer is sunnier.

Things to do in Vannes: the walled town
The ramparts, their gardens and the old wash-houses
The old town is still enclosed by its ramparts. At their foot lie formal French gardens, facing the old covered wash-houses by the water and the Tour du Connétable. This is the best-known view of Vannes and the best starting point for a walk. The gardens host several events during the year, including a book fair in June and a large gathering of Celtic dance groups in spring.
Porte Saint-Vincent and the harbour
The main entrance to the old town, Porte Saint-Vincent faces the marina. The quays and the harbour esplanade link the walled town to the gulf: this is where water-jousting contests are held and where, on the right bank, you will find the Carmes auditorium.
Saint-Pierre cathedral and the half-timbered houses
The walled town clusters around Saint-Pierre cathedral, which holds the tomb of Saint Vincent Ferrier; together with the church of Saint-Patern, a stop on the Tro Breiz pilgrimage, it is one of the town’s two great pilgrimage sites. Around it, pedestrian streets are lined with half-timbered houses, especially on Place Henri-IV. Look up to spot the « Vannes et sa femme » sign, two painted stone busts that have become a symbol of the town and whose origin remains unknown.
La Cohue, the fine arts museum
Opposite the cathedral, La Cohue (from a Breton word for covered market) was a market hall in the Middle Ages and hosted the Estates of Brittany ten times between 1431 and 1703. The building has been the town’s fine arts museum since 1982. Opening hours and exhibitions are listed on the Vannes town website.
Around Vannes: the Gulf of Morbihan and the coast
The Gulf of Morbihan is a small inland sea dotted with around fifty islands, two of which are municipalities in their own right: Île-aux-Moines and Île-d’Arz. Passenger boats stop at the islands or cruise around the gulf; operators, timetables and seasons are published by the Golfe du Morbihan-Vannes tourist office. The table below places the main sights in relation to central Vannes.
| Place | Why go | Straight-line distance from Vannes |
|---|---|---|
| Larmor-Baden | Boarding point for the gulf islands | about 13 km (8 mi) |
| Auray | The port of Saint-Goustan | about 17 km (11 mi) |
| Carnac | Standing stone alignments | about 25 km (16 mi) |
| Quiberon | Peninsula, wild coast, boats to Belle-Île | about 33 km (21 mi) |
How to read it: Larmor-Baden and Auray are less than 17 km (11 mi) away as the crow flies and each makes a half-day trip. Carnac and Quiberon, to the west, can be combined in a single day; boats to Belle-Île-en-Mer leave from Quiberon.
Itinerary: Vannes and the gulf in 1, 2 or 4 days
- Day 1: the walled town (cathedral, La Cohue, Place Henri-IV), the ramparts and wash-houses in the late afternoon, dinner by the harbour.
- Day 2: one of the gulf islands (Île-aux-Moines or Île-d’Arz) or a cruise around the gulf.
- Day 3: Auray and the port of Saint-Goustan, then the Carnac alignments.
- Day 4: the Quiberon peninsula and its wild coast.
