Description
Point de départ : maison des motards, bourg de Porcaro (coordonnées GPS : 02°11’57’’O / 47°54’33’’N) Distance : 16 km - 4 h 45 A voir en chemin : 1. L’étang de la Priaudais : la tranquillité du lieu vous invite à en faire le tour et ainsi vous plonger dans la vallée de l’Oyon. 2. Le Prieuré Saint-Étienne : cet ancien grand village est l’un des principaux centres historiques du Pays de Guer. La chapelle, la plus ancienne du Morbihan (832) est classée Monument Historique. Durant la période gallo-romaine, St Etienne fut un centre administratif, militaire et résidentiel d’importance. 3. La Pierre Tremblante : non reconnu officiellement comme monument mégalithique, ce site n’en demeure pas moins mystérieux avec la fontaine limpide, sa table à sacrifice et surtout un énorme bloc en pierre. 4. La Tête de Gore : émergence rocheuse remarquable par son abrupt belvédère qui domine le cours de l’Oyon.
