Departure from Tréhorenteuc (Morbihan)
From Tréhorenteuc to Trécesson, this route explores the southern part of the Forest of Paimpont and, first and foremost, the Val sans Retour. These are places steeped in Arthurian legend and provide a magnificent setting for a walk that is largely through forest.
Please note that during the hunting season, certain parts of the route may be closed to walkers.
