From Brest to Nantes in 11 days, cross an authentic and bucolic Brittany by bike

The Nantes to Brest canal starting from Brest offers you a beautiful crossing of Brittany! It is in the port of Brest that you start this bike tour. The adventure begins with a sea crossing of the Brest harbor to reach the Crozon peninsula.

It’s on a hilly course, with a rich natural heritage, that you arrive in Châteaulin and quickly reach the towpath. At a speed a little faster than a barge, you follow a bucolic route. The locks punctuate your stages without forcing you to stop. 238 in total, they grant water management, its flow in hilly areas. The relief is mild at the edge of this long interior artery of Brittany.

450 km between Brest and Nantes, including 364 km between the Châteaulin lock and that of Nort-sur-Erdre. What makes this cycling route rich is the variety of rivers that are ridden on more often natural than artificial. In fact, only 20%, or 73 km, have been dug to connect the rivers including the Aulne, the Oust and the Erdre. You are in the heart of Brittany and you cross a route accessible to all thanks to the maintained hauling combining combining asphalt roads, 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.

Day 7

From PONTIVY to JOSSELIN 50km 118m Niveau Loisir

Later on, as you face the cliffs of the Ile aux Pies, which lie on the other side of the canal, Brittany shows you just how surprising she can be.

Day 9

From REDON to LE GAVRE 50km 134m Niveau Loisir

After its confluence with the Oust, the Vilaine widens significantly. The bucolic towpath offers you the chance to pedal through protected, canalized wetlands. It’s an opportunity to discover the fauna and magnificent bird species that particularly appreciate these tranquil spaces. Arriving in the Loire Atlantique department, you leave the Vilaine to pedal along the canalised section of the Isac. Its banks, with their picturesque views over meadows, fields, woods and rural landscapes, brighten up your cycling trip. The Isac takes you to Guenrouet, where you can relax by the Etang de la Roche. You continue along the winding Isac, where one lock follows another, before returning to a more linear course as far as Blain. Take the time to visit the Château de la Groulais, an ancient medieval fortress that has retained all its architectural features. It’s here that you leave the Isac canal to reach what’s known as the water-logged green lung: the Gâvre forest. This is where you find your accommodation.
