The Coastal path

The GR 34 hiking trail in La Trinité sur Mer 

This is the most popular hike in La Trinité sur Mer, a Sunday afternoon rendezvous. It uses in part the GR34, the hiking trail that follows the entire coast of Brittany for almost 2000 kilometres. In Morbihan, the circuit runs along the entire Rhuys peninsula, the Gulf of Morbihan and the Quiberon peninsula. Between the salt marshes of Kervillen and the port of La Trinité sur Mer, the coastal path, known as th "Customs officers path",  winds through the most beautiful views of Quiberon Bay.
