The GR34 is an amazing walking route around Brittany. Often this is the old Customs Trail around the coast (the customs officers who guard the coast to stop smugglers), starting at Vitre (Ille et Vilaine) and finishes at Saint Nazaire.

In 2017 the Finistérienne section was elected GR favourite of the French

Information on the whole route is difficult to find. There are no Apps I can locate and no single website covering the whole of the route. This may be because individual regions within Brittany maintain the route that goes through their region.

Below are some links which may be of assistance.
