Le canal de Nantes à Brest à vélo

From Redon to Châteaulin in 9 days, cycle through autentic and bucolic Brittany

Cycling along the canal

The Nantes to Brest canal offers a beautiful journey through Brittany! On the towpath, you ride on a bucolic route at a somewhat faster pace than a barge. Cyclists, hikers, lock boaters, residents and fishermen: you will meet along the way many lovers of this land who will be happy to tell you their story of the canal.

From Nantes to Brest the canal is 450 km long with a 364 km portion from the lock of Nort-sur-Erdre to the 237th lock in Châteaulin (with a total of 238 locks*) .The richness of this route lies the variety of waterways more wild than artificial. 73 km (20%) were dug to connect the Erdre rivers like the Oust and the Alder. From Redon to Châteaulin, you are in the heart of Brittany and ride through some of the most beautiful parts of the canal on a route accessible to all thanks to the towpaths combining asphalt road, white paths and well maintained trails.

A bit of history

The construction projects of the Nantes to Brest canal were initiated under the old regime. They began under the reign of Napoleon 1st for strategic reasons. In 1804, the canal starts from both ends of Loire Atlantique (the lower Loire) and in the Finistère (the west end of Brittany). It will take 38 years to complete the work (in 1842). The operation cost 160 million gold francs in 1860, a current equivalent estimated at 150 million euros.

* 238 locks in total but none with that number: in Redon, there is a 17 bis lock; 18 were swallowed up in the construction of the Guerlédan dam in 1923.

Easy: you occasionally or regularly ride your bike and have experience in cycling for a whole day. You enjoy discovering new territories in a leisurely way. You can ride up to 35 to 55 km a day on relatively flat routes.

Day 1 - REDON

Arrival in Redon. You meet with our guide at your hotel around 6 PM for an orientation meeting.


In Redon you reach the Oust riverbank, which shares a common riverbed with the Nantes to Brest canal. The route, flat and leisurely, will let you appreciate the peaceful atmosphere of these grounds. As you face the cliffs of the Ile de Pie on the other side of the canal, Brittany shows you just how surprising she can be. At 2/3 of the route you ride through Malestroit, a small city with character. You then head on to Roc André with an impressive religious architecture. This village is also famous for its brewery Lancelot. Allow for a visit and taste a traditional beer or local Phare Ouest cola.


A fairly short day to enjoy the city of Josselin. You enter the city through its majestic castle overlooking the canal. Also labeled "Small town of character," its typical houses with timber facades offer a warm welcome. You can also rent out canoes to explore the Canal from another perspective.


You get back to the banks of the Nantes-Brest canal. As you approach Rohan you discover the Abbey of Our Lady of Timadeuc. A community of Benedictine monks lives there. They make cheeses, jams, fruit jellies ... You can discover their products within their shop. The route then takes you to Pontivy. The many locks and small retention ponds in this part of the canal are an interesting curiosity. Along the Blavet riverbanks, Pontivy offers a fifteenth century castle which was one of the Duke of Rohan residences.


You leave Pontivy to reach the Guerlédan lake and its famous hydroelectric dam. The towpath disappears here and the journey will take a bit of altitude. Before getting to the center of Mur de Bretagne, famous for his climb during the Tour de France, you take a detour to the Guerlédan lake.


You leave Mur de Bretagne and reach the canal at the level of the ancient abbey of Bon Repos (Good Rest). You then join the Forges des Salles, the highlight of the canal (184m) and the Glomel trench. The next stage takes you to Carhaix, one of the oldest Breton cities. Former capital of Poher, the city was built by the Romans. It is famous for its music festival des Vieilles Charues.


A day riding at the foot of the Black Mountains. Your get to the towpath by the Carhaix port. At the end of your journey: Castle Trévarez (which needs you to get out of the canal when you arrive in Châteauneuf). Châteauneuf-Du-Faou, built on a rocky outcrop, is your stop for the night.


A beautiful day in wild nature with mountainous area much more presen. The Monts d’Arrée and the Menez Hom one of the peaks of the Massif Armorican, are not far away. Fortunately, cycling on the towpath, you enjoy the scenery without having to climb ! You arrive on the Port Launay, the last lock.
