Balade à vélo au Boël

The vallée de la vilaine by bike

8 new cycle paths from Rennes to Laillé

A bike ride is just the ticket for getting out and meeting locals in the Vallée de la Vilaine. An experience for you to enjoy with the Grande Traversée, meaning ‘Great Crossing’, an initiative featuring new marked cycle paths from Rennes to Laillé. Over 125 km of paths and trails await here in the unspoilt countryside. Ready for the adventure of a lifetime?

The Vilaine – a vibrant valley worth visiting

The “Traversées et Escales” initiative is aimed at showcasing the Vallée de la Vilaine at its best, complete with new cycle paths cleared in Bruz, Chavagne, Laillé, Le Rheu, Rennes, Saint-Jacques-de-la-Lande and Vezin-le-Coquet. New territory for you to conquer by bike as you sail down roads and towing paths. This is the perfect opportunity to soak up key natural, farming and industrial sights and spots, meeting local farmers and taking in a patchwork of different landscapes as you go.

Nature at your doorstep

Don’t let the name fool you (‘vilaine’ means ‘dreadful’ in French): the Vilaine is a beautiful river that’s ideal for cycling. You can get to its banks easily from Rennes centre, by following the quays and towing paths. Just a few pedal strokes and you’ll find yourself on the shores of the Etangs d’Apigné lakes before heading south, dodging the hovering dragonflies as you catch glimpses of castles, mills and flower-lined locks. The Vilaine turns more sinuous as it progresses – the valley’s rolling hills emerge as you get closer to the Moulin du Boël, a mill that offers one of the most breath-taking views over the river. The Vilaine reveals its scintillating colours, shifting light under the sun. Cycle past ponds and lakes, as well as forests such as the Bois de Cicé, all hugging the banks of France’s 10th biggest river. From the banks of the Vilaine, gaze out at the many barges, canoes, kayaks and paddle boards bobbing on the waters.

The city is so close, and yet here you are, already deep in the countryside. Horses and cows watch lazily as cyclists and ramblers move through the fields, the birds are singing out, and the great crossing still has many more miles left to give.

Stop-offs at the locks and local farmers

The Grande Traversée de la Vilaine’s main route is accessible to all. Starting at the Mail François Mitterrand, it stretches over 45 km. You can complete the trail and make the return journey all in a day – as long as you set off early and make sure your bike can handle it! The towing paths are flat and wide enough for visitors hoping to tow children behind them in a bike trailer. Some of the circuits, however, are much more challenging, and are just the thing for mountain-biking enthusiasts (read on for more details).

Original circuits for curious minds and foodies

One of the striking features of these different itineraries is that they encompass heritage sites and real-life, authentic places where locals live and trade, farms, market gardens, local farmsteads where you’ll be able to refuel with Breton specialities and fruit and vegetables grown in the valley.

Guide to the grande traversée

Special signs marked in red for the main route and in purple for the 7 other circuits are here to guide cyclists throughout their experience. A general map is also available from the Rennes tourist office (11 Rue Saint-Yves) and in the town halls in the municipalities you’ll be passing through. The Grande Traversée was officially launched on Saturday 8 and Sunday 9 July 2017, with a bivouac, buffet and star-gazing session. 

If you lose your way, the best thing to do is get back to the Vilaine’s towing paths so you can make your way back to the main route. Don’t forget a helmet, reflective vest and plenty of water and sun cream.

The Grande Traversée was designed and set up by cultural cooperative Cuesta in partnership with La Petite Rennes, Cassiopée Astronomie, les Cartoucheries, la fête du Champ à l’assiette, les Tombées de la Nuit, Vents de Vilaine and Destination Rennes. The Ter agency runs this project locally. The illustrations are the work of Rennes-based artist MioSHe. The maps were drafted by Léa Muller.
