Cycling along the canal

From Redon (Nantes) to Châteaulin (Brest) in 9 days, cycle through autentic and bucolic Brittany

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.

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.
After few kilometers, you enter the city of Josselin 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.
