Starting from the small oyster port of La Roche-Jaune, this route takes you on a journey of discovery through the Jaudy estuary, the Lizhildry valley and the Plouguiel countryside.
Please note that the return route along the estuary is not accessible at high tide; you will need to follow the alternative route by road.
After 6 km, a shorter alternative route takes you directly back to La Roche Jaune via Convenant Ty Tano.
Yellow markings (and red and white on the coastal section GR3®4), anti-clockwise.
