Created in 1791, the path was patrolled by customs officers – hence its name – tasked with preventing any smuggling. To keep an eye on trafficking and looting of wrecks, they crisscrossed the coasts night and day, whatever the weather. Having fallen into disuse at the beginning of the 20th century, the path was given a second lease of life in 1968, when a few enthusiasts decided to turn it into a hiking trail. It was near Lannion that the famous white and red markings that mark the route appeared: the GR® 34 was born.
