If you want to hike a section of Brittany’s Emerald Coast that is truly rugged and beautiful, look no further than this walk. The walk begins and ends in Cancale, the oyster capital of Brittany. It combines dramatic coastal views with the region’s famous seafood.
Cancale is the oyster capital of France. Louis XIV famously ordered his oysters from here, and today the town remains one of the most important shellfish ports on the Emerald Coast.
Steeped in history and a long tradition of fishing, the people of Cancale are proud of their reputation and it isn’t hard to figure out why. Either start or end your hike at the oyster market. Look for the lighthouse at the end of the harbour, flying Cancale’s green flag decorated with a ship surrounded by oysters.
This coastal hike from Cancale to Pointe du Grouin explores one of the most rugged stretches of Brittany’s Emerald Coast. Beginning in Cancale, the famous oyster port overlooking the Bay of Mont-Saint-Michel, the route follows the GR34 past hidden coves, sandy beaches and dramatic cliff-top viewpoints.
The walk reaches its climax at Pointe du Grouin, a windswept headland with sweeping views across the bay, before returning inland through woodland and the town of Cancale itself.
Route Description
This hike begins at the Cancale oyster market, where the GR34 coastal path climbs above the harbour before heading north along the Emerald Coast.

Before reaching the larger sandy beach at Port Mer, with several restaurants; a popular stopping point for swimmers and walkers.
Beyond Port Mer the cliffs grow more exposed as the path approaches Pointe du Grouin, a dramatic rocky headland overlooking the Bay of Mont-Saint-Michel.

The final section descends back into Cancale, passing through the town before returning to the harbour and oyster market where the walk began.

Points of Interest
- Marché aux Huîtres de Cancale: Cancale’s famous oyster market sits directly on the harbour front and is the best place to taste oysters fresh from the bay. Choose between flat oysters (huîtres plates) and round oysters (huîtres creuses), add a squeeze of lemon and enjoy them overlooking the sea.
- Islands of the Bay: Just offshore from the hiking trail lie several small islands. The most striking is Île des Rimains, home to an 18th-century fort and now a private island. Nearby Île des Landes is a protected bird sanctuary where seabirds nest undisturbed along the cliffs.
- Pointe du Grouin: The name “Grouin” comes from the Breton word grouin, meaning “snout”, a reference to the shape of the rocky headland projecting into the sea.
- Bay of Mont-Saint-Michel: Along this route you are looking across the wide Bay of Mont-Saint-Michel. The famous abbey itself lies just across the border in Normandy and has been a UNESCO World Heritage Site since 1979. On clear days you may be able to spot the distinctive silhouette of the abbey rising on the horizon.
- Église Saint-Méen: On the return through town the route passes Église Saint-Méen, located in the centre of Cancale. The square nearby hosts the town’s lively Saturday market, where local producers sell seafood, vegetables, cheeses and Breton specialities. In front of the church stands the Fontaine des Laveuses d’Huîtres, commemorating the women who once washed oysters from the bay before they were sold in the market below.
