The Marais Blanc by bike

Pedal along the Digue de la Duchesse Anne from Saint-Benoit des Ondes to the Chapelle Sainte-Anne, with a view over the Bay of Mont-Saint-Michel. Your route will be punctuated by sights and wonders!

An authentic encounter with the Bay of Mont Saint Michel

Pure cycling pleasure!

Here’s a really lovely ride this 20km bike ride.
Yes you won’t see the miles go by, firstly because it’s all flat and then above all because you’ll get an eyeful. Marshes, biez, greenway, Mont Saint Michel, crops in shambles …

La voie verte, kingdom of the cyclist

On the seafront, take in the sea air between a visit to the Moulin de la Ville Es Brune and a stop off in the small market town of Hirel to discover sand yachting. The Bay of Mont Saint Michel, a UNESCO World Heritage site, is one of the most beautiful bays in the world, so make the most of the exceptional panoramic views.

A land of milk and honey where everything grows!

The Marais Blanc is the drained part of the marsh located just behind the Duchesse Anne dyke, the dyke that has frozen the current coastline since the Middle Ages. It is part of the Dol marsh, which covers 12,000 hectares. It is made up of soil composed of marine alluvium and clay, which gives it its light colour. Situated below sea level, water control is a priority here. The marsh is criss-crossed by several kilometres of biez or navigation channels that used to be used to transport wood, reeds or fodder when the roads were impassable!

Light-coloured, rich soils where everything grows, from cauliflowers to potatoes and all root vegetables. Everywhere you turn you can stock up on good vegetables and in all seasons, producers practising direct sales.

From small stone bridges to locks along the biez

In the southern part, you follow the Biez du Milieu, a canal that drains the marsh at this point below sea level, with typical reedbed landscapes that are home to particular wildlife. The landscape is dotted with numerous stone (granite) bridges built to cross the main biez, such as those at Le Rosais and La Goutte. They are of fairly high architecture, which used to allow barges to pass. Today, they are used to explore the marsh on foot or by bike.

The middle biez, 3.5 km long, is marked by 2 locks at its ends. The very ingenious system of sluices for managing water levels is managed by the Syndicat des Digues et marais.
