The Sentier des Douaniers (Custom’s Officers’ Trail) is exactly what it says it is: A coastal footpath devised in the 1700s to foil smugglers.
If you wanted you could start from Saint-Malo and walk all the way to Brest in Finistère.
But you may need to allow 25 days to walk these 400 kilometres, so it’s not exactly a day trip! Instead you could pass a memorable day hiking the Côte d’Émeraude (Emerald Coast), on either side of Saint-Malo.
You’ll encounter pale windswept beaches, granite cliffs, meadows flecked with wildflowers, oyster and mussel beds and many bunkers and pillboxes from the Second World War.
