Walking the Brittany Coast Path

The GR34 from Mont-Saint-Michel to Roscoff

Guidebook detailing a 624km section of French long-distance route the GR34 (or Sentier des Douaniers, the Customs Officers' Path) along the scenic north coast of Brittany from Mont-Saint-Michel to Roscoff. The popular well-maintained trail takes in cliffs, beaches, seaside resorts and fishing villages and is rich in history and culture.


The GR34 can be hiked at any time of the year, but - taking into account weather and holiday crowds - the best periods are late spring and early autumn.

There are no technical challenges on the GR34; any fit walker can enjoy this trek. The GR34 is not a mountain trail: there are extensive sections of level walking. The trail does, however, climb and descend many slopes - never very long but steep in places.

By Carroll Dorgan

Carroll Dorgan was born and educated in the United States. Pushed by the absence of jobs for inexperienced history graduates where he happened to be living in 1975 and pulled by his wanderlust, Carroll pursued a teaching career for a decade in international schools in Iran, Belgium, England and France. He then returned to California to qualify as a lawyer, but soon moved back to Europe to practice international law in the Netherlands and France. In all of those places, he explored nearby hiking trails. Now retired, he can devote time to writing about those trails.
