The Saint-Malo to Cancale ride is a classic cycling excursion on the Emerald Coast. 18 kilometres of varied scenery, an arrival at the port de la Houle and its famous oysters, and the option to push on to the Pointe du Grouin for a 360-degree view of the Mont Saint-Michel bay. This guide details the route kilometre by kilometre, including the roads, points of interest, and our tips for making the most of it.
We ride this route several times a month, in every season. Every detail in this guide comes from our direct experience on the ground.

The route kilometre by kilometre
Km 0-3: Le Sillon to Rochebonne
Cycle track then cycle lanes • Flat • Easy
Start at the old town end of the Sillon, facing the sea. A two-way cycle track runs along the road for about 700 m, then cycle lanes take over, in a 30 km/h zone. On the seawall promenade itself, bikes go at walking pace. The wooden wave-breakers line the left, Belle Epoque villas on the right. This is the warm-up section: pleasant and effortless.
Km 3-6: Rochebonne to Rothéneuf
Cycle lanes • Gently rolling • Easy
Cycle lanes continue along the road through Parame (Avenue Kennedy, Boulevard de Rothéneuf) to Rothéneuf. You ride next to the cars, but at reduced speed. You pass near the carved rocks of Rothéneuf (short detour, paid entry).
Km 6-12: Rothéneuf to Saint-Coulomb
Minor roads • Shared with cars • Moderate
You leave the urban area for the countryside of Saint-Coulomb, on minor roads shared with cars and without a cycle path. Take care crossing the departmental roads, which are busy in summer. Part of this stage is a provisional route: 8 of the 18 km, according to France Vélo Tourisme. With a headwind, this is where an electric bike makes the biggest difference.
Km 12-18: Saint-Coulomb to Cancale
Minor roads • Gently rolling • Moderate
Beyond Saint-Coulomb you continue on minor roads towards Cancale. At the fork at Les Boulais, the Vélomaritime loop into Cancale is not signposted: keep a map or GPS to hand. For the coves of La Guimorais and Port-Mer, plan a detour towards the coast. There is little climbing on the whole route: 44 m in total, with a highest point of 48 m.
Arrival: Cancale and the port de la Houle
Descent to the port • Easy
The arrival in Cancale is a magical moment. The road descends towards the town with a sweeping view of the bay, the oyster beds stretching to the horizon, and Mont Saint-Michel in the distance on clear days. You ride down to the port de la Houle: this is where the oysters await.
Arriving in Cancale: oysters at the port
The port de la Houle is the heart of Cancale. Around ten oyster farmers' stalls line the quayside, each offering their flat and cupped oysters, freshly harvested from the beds. Pick a dozen (5 to 8 euros depending on size), sit on the harbour wall facing the bay, and enjoy with a lemon and perhaps a glass of Muscadet from the bistro next door. Simple, authentic and delicious.
Our tip
The stalls are open daily in season, with reduced hours off-season. Cupped oysters no. 3 (standard size) cost 5-6 euros per dozen. Flat oysters (Belon) are pricier (10-12 euros per dozen) but have an incomparable flavour. The stall furthest to the right as you walk down to the port is often the least crowded — same quality, less waiting.
Optional: Pointe du Grouin (+10 km round trip)
The Pointe du Grouin is a headland north of Cancale, at the edge of the Mont Saint-Michel bay. From Cancale, it is 5 kilometres further north, with a short, steep final climb. The reward matches the effort: a 360-degree panorama of the bay, Mont Saint-Michel, the Chausey Islands, and the coastline as far as Cap Fréhel on clear days. You may spot colonies of cormorants and, with luck, dolphins in the bay.
Our tip
With an electric bike, the final climb is no problem. On a regular bike, the final climb is often walked: no shame in it. Bring a windbreaker: at the top of the Grouin, the wind always blows. Arrive early in the morning (before 10 am) or late in the day for the best light and fewer crowds.
Getting back: 3 options
Option 1: Cycle back (recommended)
Same route in reverse. The prevailing wind (north-westerly) is often in your face on the return, so save some energy. The climbs from the outward journey become descents. Allow about 1h15 or more, depending on the wind.
Option 2: The bus, without the bike
Cancale is served by the MAT bus network (line 5), but MAT does not accept bikes on its buses. Combine it with option 3 if your legs have had enough after the oysters and the Grouin.
Option 3: Bikey Rent pick-up
We can arrange to collect your bike in Cancale. Get in touch in advance for conditions and availability.
Frequently asked questions
How long does it take to cycle from Saint-Malo to Cancale?
France Vélo Tourisme counts about 1 hour 15 for the 18 km, on roads shared with cars, with cycle lanes on the Saint-Malo side. Add 30-45 minutes for the Pointe du Grouin (5 km more with a steep climb).
Is the ride difficult?
Moderate, mainly because of the traffic. There is little climbing (44 m in total, highest point 48 m), but the whole route is on roads shared with cars, with busy departmental roads to cross in summer, and the official Vélomaritime website gives this stage its toughest rating. The first 6 km (Sillon to Rothéneuf) have cycle lanes along the road. An electric bike makes headwinds and the short climbs easy.
Is there a cycle path from Saint-Malo to Cancale?
Not really. France Vélo Tourisme classes the whole route as shared road, including 8 km of provisional route. In Saint-Malo, a cycle track and then cycle lanes run along the road from the Sillon to Rothéneuf (about 6 km); after that you ride minor roads via Saint-Coulomb. The route is waymarked with the Vélomaritime logo, but the loop into Cancale is not signposted.
How do you get back from Cancale?
Cycle back the same route (18 km, often into the prevailing north-west wind), take the MAT bus (line 5) without your bike, as MAT buses do not accept bikes, or arrange a Bikey Rent pick-up on request.
