GR® 34, the Sentier des Douaniers (customs officers’ path)
Tour of Brittany on foot
This is one of the most iconic pathways of the French Grande Randonnée® (GR) hiking trail network. The GR® 34 ‘sentier des douaniers’ runs for more than 1,800 km along the entire Breton coastline, featuring stunning views over the sea. An unforgettable experience!
A trail that’s packed with history
The ‘sentier des douaniers’ was created back in 1791 to criss-cross the coastline and prevent the smuggling of contraband goods. The path fell into disrepair in the early 20th Century, but has enjoyed a new lease of life since 1968, with the appearance of the famous red and white trail markings close to Lannion, that act as signpost markers for the route. Nowadays the GR® 34 runs all around the Breton shoreline from the Mont-Saint-Michel to the Arzal barrage (Morbihan).
A succession of picture-postcard views
Rocky outcrops, wilderness coastlines, marshland, dunes, beaches, creeks, diverse flora and fauna and a rich historical heritage… there’s a picture-postcard view at every turn. Walking on the GR® 34 is the one of the best ways to capture the spirit of Brittany and feel the invigorating breath of the wide-open air. Get ready for a visual feast: see Mont Saint-Michel Bay, the Emerald Coast and the Pink Granite Coast, the ‘Abers’ of Finistère, the Crozon peninsula, the Cornouaille coast and the Pointe du Raz, Southern Finistère and the Gulf of Morbihan.
More walks to enjoy through Brittany
You can also explore other Grande Randonnée® trails that criss-cross the region. The GR® 37 crosses Brittany from East to West, from Vitré to the Crozon peninsula, via the legendary forest of Brocéliande, the Nantes-Brest canal and the Monts d’Arrée mountain range. Still travelling East to West is the GR® 38, linking Redon to Douarnenez, while the GR® 39 snakes its way North to South following the course of the River Vilaine from the Mont Saint-Michel to Guérande. Then there’s the GR® 380, which makes its way around the stunning Breton mountain range: the Monts d'Arrée. You could also explore the pathways of the Grande Randonnée de Pays (GRP) hiking trails: they form loops so that you can return to your starting point.
