Cycling day trip from Roz-sur-Couesnon to St-Malo

Set off from Roz-sur-Couesnon, a charming village in Brittany not far from the world-famous Mont-Saint-Michel marshes. The route rolls gently west towards the beautiful walled city of St-Malo, covering about 43 kilometers—ideal for a relaxed day’s ride.

You’ll cruise mostly on quiet roads with some stretches of gravel and unpaved tracks, so a sturdy bike and a bit of adventurous spirit are handy. The ride is mostly flat with just a few mild climbs and more descent than ascent. Along the way, soak in sweeping views of the Bay of Mont-Saint-Michel and the countryside, maybe even spot some salt marsh sheep!

Arriving in St-Malo, you’ll be greeted by impressive granite ramparts and the endless Atlantic horizon. It’s a historic pirate city with plenty to explore, from sandy beaches to creperies and cobbled lanes—perfect for a well-earned treat after your ride.
