The customs path on the Pink Granite Coast
Frequently asked questions- What is the customs path?
The GR® 34, also known as the customs trail, runs for more than 2,000 kilometres along the coast of Brittany. It starts at Mont-Saint-Michel, in the Manche département, and stretches as far as Saint-Nazaire, in the Loire-Atlantique département. Initially, it meandered inland, but today it follows the coastline exclusively. The trail passes through a variety of landscapes, from the Bay of Mont-Saint-Michel to the Emerald Coast, via iconic sites such as Saint-Malo and Cancale. So you can look forward to a long walk along the customs path!
- How many stages are there on the Customs Trail?
The sentier des douaniers or GR®34 is generally divided into around a hundred stages. These vary in length and difficulty, from 10 to 25 kilometres per day, depending on the section. But don’t worry: walkers can adapt their itinerary to suit their level of fitness and the time available! Some stages are easier and more accessible, while others have a greater positive difference in altitude and require good physical preparation.
- Where can I find out more about the Customs Trail?
For more detailed information on the Customs Trail, contact us or visit the tourist office.
You can also visit the Mon GR website, which specialises in hiking and roaming. - What level of ability do you need to set off on a hike along the customs trail?
The GR®34 is accessible to all, but some sections require a good level of preparation. Beginners can start with easy stages such as Lézardrieux to Sillon de Talbert, with flat, well-marked paths. Intermediate hikers will enjoy the more varied terrain between Tréguier and Plougrescant. The difficult sections, such as Ploumanac’h to Trégastel or Trédrez, require a good level of fitness because of the steep paths and the steep gradients. Good physical condition and the right equipment are essential if you are to enjoy the route to the full.
- Can you cycle the customs trail?
Cycling is prohibited on the coastal path, which makes up most of the GR®34.
However, for cycling, there are cycle routes nearby, such as La Vélomaritime (EuroVelo 4), which allow you to cycle between Lézardrieux and Plestin-les-Grèves. The Vélomaritime mainly follows minor roads and includes sections of greenways. - What do I need to take with me on a hike along the customs path?
Be sure to check out the various water points on your route before you set off and plan your supplies accordingly. And don’t forget your camera to capture the magnificent landscapes of the Pink Granite Coast!
- Where can you eat on the customs trail?
To eat, you can either prepare your picnic beforehand, or indulge in the flavours of Brittany by visiting one of the restaurants on your route. Hiking also means the freedom to choose where to eat!
- On which beach can you take a break along the customs path?
If a few kilometres on foot wears out your shoes, enjoy a short break on one of the beaches of the Pink Granite Coast:
💦 La plage de Goas Lagorn (Lannion) : Its fine sand and beautiful waves will delight surfers and body-boarders as well as families.
💦 La plage de la Grève Blanche (Trégastel) : A lovely spot for a break, with fine sand and clear waters. Perfect for a swim after a hike!
