The 3-Day Brittany Itinerary Worth Skipping Mont Saint-Michel For
Saint-Malo gets the postcards. Mont Saint-Michel gets the crowds. Vannes gets three days of real travel.
A stunning medieval walled city on the southern coast of Brittany, right at the edge of the Gulf of Morbihan, a semi-enclosed sea with more than 40 islands.
The old town is beautifully preserved, the market is one of the best in France, and you can be on an island 45 minutes after breakfast.
Three days here is enough to understand why people who find it tend to come back.
Day One: The Old Town
Start with the ramparts. The defensive walls around Vannes’s historic center date back to the Romans in the 3rd century and have been added to ever since.
You can walk sections of them for free, and the Jardin des Remparts below, tucked into the old moat with flower beds and the Marle river running through it, is one of those rare sights that doesn’t feel like it’s been staged for tourism.
Inside the walls, Place Henri IV is worth a slow look. Two half-timbered buildings almost lean into each other across the square, with the spire of Saint-Pierre Cathedral rising behind them.
The covered market, Halles des Lices, is open Tuesday, Wednesday, Friday, and Saturday mornings from 8am to 1pm.
One hall is dedicated almost entirely to seafood: scallops, crabs, oysters from the Gulf of Morbihan, whatever came in that morning.
The Wednesday and Saturday outdoor market wraps around it and across the historic center. Show up hungry.
The fish market hall is open year-round, on Tuesdays, Wednesdays, Fridays, and Saturdays, even when the outdoor market isn’t running.
Where to Stay
Maison de la Garenne is a 19th-century B&B just outside the old walls, a five-minute walk from the ramparts and a short walk to the port.
Reviewer praise the hosts Christine and Antoine for their useful restaurant recommendations and the quality of the breakfast, served on white tablecloths with hand-painted Breton ceramics.
There are no hotels inside the walled city, so this is about as close as you’ll sleep to the medieval center.
For something with a view of the water, Best Western Plus Le Roof sits on the Conleau peninsula, about 4.5km from the center. The setting is a recurring obsession: rooms with balconies overlooking the anchorage, boats moored below, a brasserie next door doing fresh seafood.
Get a sea-view room or don’t bother. Multiple reviewers describe it as better than hotels twice the price.
Day Two: Île-aux-Moines
The Gulf of Morbihan contains over 40 islands, and Île-aux-Moines is the most accessible from Vannes.
It’s the largest island in the Gulf at about 7 square kilometers. People rent bikes at the port and spend four hours finding coves they weren’t looking for.
From Vannes, take the Line 23 bus from the main bus station toward Baden. The ride is about 20 minutes, then a short walk to Port Blanc for the ferry. The crossing takes five minutes.
Izenah Croisières runs shuttles every 30 minutes, and the round-trip cost for a family of four was around €20 in 2023. Cars need special authorization from the island’s town hall, so almost everyone gets around on foot or by bike.
There’s a village, a few cafes, and the Cromlech de Kergonan, a Neolithic stone circle that most visitors walk straight past.
The last ferry back to the mainland runs around 6pm. Don’t cut it close.
Day Three: Carnac
About 35 kilometers southwest of Vannes, Carnac is home to the largest concentration of megalithic monuments anywhere.
More than 2,000 menhirs arranged in long rows across three main sites, Ménec, Kermario, and Kerlescan, built somewhere between the 5th and 3rd millennium BC. UNESCO granted it Heritage Site status in 2025.
The Maison des Mégalithes visitor center is free to enter and has video presentations and exhibitions about the site’s history. From October to March, you can walk directly into the stone fields at no cost.
From April to September, the alignments are fenced off to protect them, and access is by guided tour only.
English-language guided tours run daily at 3:30pm in summer (1pm from August 23 onward). Tickets run around €13 in high season.
Even without a guided tour, the footpath around the perimeter of the Ménec and Kermario alignments lets you walk alongside the stones and get a real feel of the scale.
The Pass des Mégalithes covers the Carnac alignments plus four other nearby sites, including the Cairn of Gavrinis and the Locmariaquer megaliths, with a single paid entry unlocking the rest for free.
Parking fills up fast in summer. Arriving before 9am is not an exaggeration as advice.
