GR®34 – Customs Trails
The GR34, also known as the customs officers’ trail, is one of the most iconic hiking trails in France. It runs along the entire Breton coast for over 2,000 km. This white-and-red marked trail crosses wild landscapes, picturesque ports, and a unique maritime heritage. From the bay of Mont-Saint-Michel to the Saint-Nazaire bridge, it offers a total immersion in the Breton world.
The GR34, a spectacular route between land and sea
The GR34 trail follows the old coastal patrol paths used by customs officers since the 18th century. Today, it is one of the longest long-distance hiking trails in France. Most hikers travel it from north to south, starting near Mont-Saint-Michel.
The GR34 route crosses Côtes-d’Armor, Finistère, Morbihan, and Loire-Atlantique. It can be completed in its entirety over several weeks, or in sections, particularly by choosing a one-week GR34 route. Each section offers a different charm, featuring steep cliffs, fine sandy beaches, wild abers, and small, colorful harbors.
It’s perfectly possible to explore the GR34 in a week, with several accessible GR34 trails:
- From Saint-Brieuc to Lannion : coves, beaches, and granite scenery along the Emerald Coast
- From Douarnenez to Quimper via Pointe du Van : wild nature and Breton tradition
- From Vannes to Auray : gentle coastal trails in Morbihan

Please note that the routes are suitable for hikers of all levels. Access to the stopover towns is easy thanks to the rail network and regional buses.
In addition, the GR34 was voted “France’s Favorite GR 2018” in the national competition My Favorite GR organized each year by the FFRandonnée.
Accommodation on the GR34: where to stay?
The GR34 accommodation is one of the great strengths of this route:
- Stopover lodges or B&Bs
- Campsites or bivouac areas
- Hotels in the towns and ports visited
Some accommodation providers offer services adapted to hikers: evening meals, luggage transfer, drying of clothes.
Remember to book in advance during high season, especially on busy sections like the Pink Granite Coast or the Crozon Peninsula.
