A walk on the Brittany coastline from the World Wonder Mont St Michel to St Malo. Walk the famous custom's path and enjoy bird watching and exceptional views.On one side, rocky points, wild coastline, dunes, beaches and coves. On the other side, marshes, a variety of fauna and flora, a rich historical heritage... and always the sea or the ocean in the background. Every bend on the GR34 plunges you into a new postcard. As you walk, the spirit of Brittany invades you, and you feel invigorated by the ocean breeze.Created in 1791, the path was travelled by controls of customs officers - hence its name - in charge of preventing smuggling. To keep an eye on trafficking and on the pillaging of shipwrecks, they strode up and down the coastline, night and day, in all weather: think of this when your legs are tired! After falling into disuse in the early 20th century, the path experienced a revival in 1968, when a few passionate walkers decided to make it into a walking route. Today it goes all around the Brittany coastline, from Mont-Saint-Michel to the bridge of Saint-Nazaire. This path leaves a permanent mark on anyone who walks it.
