Circuits and walks in the Gulf of Morbihan

The Gulf of Morbihan is a favourable terrain to enjoy the pleasures of hiking. It offers signposted circuits between the fine sandy beaches, on the ocean side, the rocky strikes, on the Gulf side but also in the forest of the Landes de Lanvaux. More than a hundred kilometres of paths are accessible to experienced hikers, but also to beginners and families.

GR® 34 and GRP® Valves-Lanvaux

GR34® or “Customs Trail”

GR34 for the more Cartesian, “Sentier des douaniers” for the more intimate, the two names designate a continuous route of 180 kilometres from Locmariaquer to Arzon. Created during the Revolution to monitor the coasts and fight against smuggling, these trails now allow you to discover the must-see sites of the Gulf of Morbihan: the seven islands in Baden, the banks of the port of Vannes, the trail of the Culs salés in Séné, the marshes of Séné in Saint-Armel, the Petit Mont in Arzon… On the ocean side, the GR 34 continues along the cliffs of the Grand Mont in Saint-Gildas de Rhuys, along the banks of the river Pénerf at Tour-of-Parc or the marshes of the castle of Suscinio.

The 10 commandments of the hiker

  • Respect the trails and don’t look for shortcuts. Walking off trails degrades the environment and worsens natural erosion.
  • Do not leave any trace of your passage. Take your rubbish with you to the nearest dustbin.
  • Keep your dog on a leash. Respect the peace and quiet of the herds and do not disturb pets.
  • Do not throw away your cigarette butts. They are huge dangers at the slightest passing breeze.
  • Check the local weather forecast and prepare accordingly.
  • Notify someone close to you of your itinerary.
  • Learn to recognise the fauna and flora to enhance your hike. Knowledge of the natural environment allows you to better understand why you should respect it.
  • Close the gates and fences on your route. The municipal staff have built them to preserve the landscape.
  • Do not consume water from fountains or streams. Their apparent limpidity does not necessarily mean that they are drinkable.
  • Find out about the regulations of the nature and ornithological reserves and respect the tranquillity of the place and the animals.
