The GR® 34, nicknamed “the Customs Trail”, is one of France’s most iconic long-distance GR footpaths.

The 1800 km path follows the coastline of Brittany from Mont Saint-Michel to the Arzal Dam in Morbihan, with non-stop stunning views of the sea. Created during the French Revolution to watch over the coasts and prevent smuggling, hikers can today discover exceptional sites along the trail.
