For a first stay or a family trip, choose Belle-Île-en-Mer, the largest and most complete of Brittany’s islands. Ouessant is the end of the world, lighthouses and storms included; car-free Bréhat makes a perfect day trip among mimosas and pink rocks. The six others — Groix, Glénan, Batz, Île aux Moines, Sein and Chausey — answer more specific wishes: a lagoon beach, a one-day escape, total silence.
By The Dem-Tukki editorial team·Published ·Updated ·8 min readAround fifteen inhabited islands dot the coasts of Brittany, from the Channel to the Gulf of Morbihan, and nine of them have their own guide on Dem-Tukki. They all look a little alike — heathland, lighthouses, coves, crêperies — and yet none is experienced the same way: you spend a week on Belle-Île, a day on Bréhat, and come back from Ouessant feeling you have touched the edge of Europe. Here is how to choose.
🏝️ Belle-Île-en-Mer — The most complete
Forty-five minutes from Quiberon, Belle-Île lives up to its name: 85 km² of heath and valleys, four villages, a Vauban citadel at Le Palais, a picture-postcard harbour at Sauzon, and a wild coast whose Port-Coton needles inspired Monet. It is the largest of the Breton islands, and the only one where you can spend a week without ever repeating a walk: Donnant beach for surfers, the coves of Port-Kérel, the Pointe des Poulains with Sarah Bernhardt’s fort, and an 80 km coastal path around the island.
It is the ideal island for a first stay: hotels, campsites and rentals at every price, restaurants open in season, summer buses, bike hire right off the boat. You can bring a car, but an electric bike is more than enough and spares you the boarding queues. Find addresses and tips in our Belle-Île-en-Mer guide.
🗼 Ouessant — The end of the world
“Whoever sees Ouessant sees their own blood,” goes the sailors’ proverb. Twenty kilometres off the tip of Finistère, Brittany’s westernmost island closes the Iroise Sea, a UNESCO biosphere reserve: fifteen square kilometres of treeless heath, free-roaming sheep, eight hundred inhabitants around the village of Lampaul and five lighthouses, including Créac’h, one of the most powerful in the world. People come for the storms as much as for the light, and leave feeling they have seen the end of Europe.
Allow 1 h 15 by boat from Le Conquet or 2 h 30 from Brest with Penn Ar Bed, or a twenty-minute flight from Brest. On the island, cars are for residents only: hire a bike at the Stiff landing stage and circle the island in a day, though two or three nights let you see the Lighthouse and Beacon Museum, the Niou eco-museum and the Pern cliffs at sunset. Our Ouessant guide details accommodation and timetables.
🌸 Bréhat — The car-free island of flowers
Ten minutes by boat from the Pointe de l’Arcouest near Paimpol, and you step into a garden: mimosas from February, agapanthus and hydrangeas in summer, fig trees and eucalyptus all year round, thanks to a microclimate kept mild by the Gulf Stream. Bréhat is in fact two islands joined by a bridge, with pink granite rocks, a hilltop chapel (Saint-Michel), a lighthouse at the far end (the Paon) and not a single car.
Its small size — 3.5 km long — makes it the day trip par excellence, on foot or by bike, with a boat tour around the island to admire the coast. Visitors are many in summer: come early, or stay overnight to enjoy the island once the last boat has left. Addresses and crossings in our Bréhat guide.
🧭 The six other islands, in a few words
The “small” Breton islands are no second choice: they suit travellers who know what they are looking for.
Groix, 45 minutes from Lorient, is the island of tuna boats and lobsters, with a geological curiosity — the convex Grands Sables beach, which shifts with the storms — and a nature reserve famous among mineralogists. Three days pass there without a dull moment.
The Glénan archipelago, off Concarneau, is the “Breton Caribbean”: white sand, turquoise lagoon, a world-famous sailing school and an endemic narcissus that blooms in April. It is a day trip, April to September, by boat from Bénodet, Concarneau or Loctudy.
Île de Batz, a quarter of an hour from Roscoff — and its Brittany Ferries terminal — hides an exotic garden, the Georges-Delaselle garden, quiet beaches and fields of early vegetables. Perfect for a day, or a peaceful night.
Île aux Moines is the pearl of the Gulf of Morbihan: a five-minute crossing from Port-Blanc, sheltered coves, the Bois d’Amour and a Neolithic stone circle. Car-free, by bike or on foot, ideal with children.
Île de Sein, an hour from Audierne, is the “island of free men”: a flat rock of less than one square kilometre, with no cars and no trees, where you walk between huddled houses, the Goulenez lighthouse and the memory of the fishermen who sailed to join de Gaulle in London in 1940. For silence, and lovers of the world’s end.
The Chausey islands, Norman but an hour from Granville and neighbours of Brittany, form Europe’s largest archipelago at low tide: some fifty islets at high water, several hundred at low water. The Grande-Île is a day trip, with a handful of rooms and cottages for those who want to watch the tide come in.
🗓️ When to visit the Breton islands?
The Breton islands have no bad season, but they have very different ones. May, June and September are ideal: long days, heath in flower or purple heather, water still cool but swimmable, rooms available and crossings without crowds. July and August bring beaches and festivals, at the cost of boats and rentals to be booked weeks ahead, especially for Bréhat, Belle-Île and the Glénan.
Winter has its fans: Ouessant’s storms, Bréhat’s mimosas in February, the great tides of Chausey. Beware of reduced services though — one or two crossings a day to Ouessant and Sein, no boats to the Glénan between October and March — and closed restaurants. Check off-season timetables on each island’s transport page.
⛴️ Getting there: crossings, car or bike?
Each island has its departure port: Quiberon for Belle-Île (Compagnie Océane, 45 min), Lorient for Groix (45 min), Le Conquet or Brest for Ouessant (Penn Ar Bed), Audierne for Sein, the Pointe de l’Arcouest for Bréhat (Vedettes de Bréhat, 10 min), Roscoff for Batz (15 min), Bénodet or Concarneau for the Glénan (Vedettes de l’Odet, about 1 h), Port-Blanc for Île aux Moines (5 min) and Granville for Chausey (1 h). From the UK, Brittany Ferries lands you in Roscoff or Saint-Malo; Batz and Bréhat are then the closest. Our “getting there” pages — Belle-Île, Ouessant, Bréhat — give companies, durations and booking tips.
Cars only cross the sea to Belle-Île and Groix, and are rarely useful there: both islands are explored by bike, summer bus or a vehicle hired on the spot. Everywhere else, you leave the car in a mainland car park — budget for it — and walk. Our pages getting around Belle-Île and getting around Groix compare the options.
👨👩👧 Which island for you?
Families: Belle-Île for variety, Île aux Moines and Batz for a safe, car-free day. Couples: Bréhat off season, Sein for silence, Ouessant for the light. Walkers: the coastal path around Belle-Île, Ouessant and Groix for the cliffs. Beaches: the Glénan without hesitation, then Grands Sables on Groix and Donnant on Belle-Île. One day only: Bréhat, Batz, Île aux Moines, Chausey or the Glénan. A week: Belle-Île, or an Ouessant + Sein duo from Finistère.

Craving the end of the world, lighthouses and wind? Ouessant is like no other.
For a timeless day out, Bréhat and its pink rocks are unbeatable — and if you dream of a lagoon, head for the Glénan between April and September.
❓ Frequently asked questions
Which is the most beautiful island in Brittany?
There is no single answer: Belle-Île is the most varied, Ouessant the most spectacular, Bréhat the most flowery and the Glénan have the finest water. The right choice depends on how much time you have and what you are after — which is the whole point of this comparison.
Which Breton island can be visited in a day?
Bréhat (10 min from L’Arcouest), Île de Batz (15 min from Roscoff), Île aux Moines (5 min from Port-Blanc), the Glénan and Chausey are the ideal day trips. Belle-Île, Ouessant and Groix deserve at least two nights.
Can you take a car to the Breton islands?
Only to Belle-Île and Groix, by reservation and at a high price. It is rarely useful there: bikes, buses and taxis suffice. Bréhat, Sein and Île aux Moines are car-free, and Ouessant reserves cars for residents.
When is the best time to visit the Breton islands?
May, June and September: frequent fine weather, fewer people, easy crossings. July-August for swimming, provided you book boats and rooms early. Winter suits lovers of storms (Ouessant) and mimosas (Bréhat), with reduced services.
Should I book the crossing in advance?
Yes in July-August and on long weekends, especially for Bréhat, Belle-Île, the Glénan and Ouessant. Off season, buying at the counter is often fine, but check timetables: some routes have only one or two sailings a day.
