The customs path on the Pink Granite Coast
Frequently asked questions- What is the customs trail?
The GR® 34, also known as the sentier des douaniers, runs for over 2,000 kilometers 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 region. Originally, it meandered inland, but today it follows the coastline exclusively. The trail crosses a variety of landscapes, from the Bay of Mont-Saint-Michel to the Emerald Coast, passing through iconic sites such as Saint-Malo and Cancale. All the ingredients for a long walk along the customs trail!
