Park near the Pont de l’Archevêque.
(S/E) Set off westwards, taking the stony path on the north side of the Chenal du Milieu. Right from the start, looking north (on the right-hand side), there is a lovely view of the wine cellars at Château Beychevelle. Further on, still on the right-hand side, there is a lovely glimpse of Château Branaire-Ducru.
(1) After nearly a kilometre, at a bridge over the Chenal du Milieu, turn right onto a track heading north towards Beychevelle. As you approach the village, at a T-junction, turn left onto a wide track sloping down towards the south. On the right, there is a lovely view of Château Gruaud-Larose and its wine cellars.
.(2) At the next junction, take the path furthest to the right, which climbs slightly north-westwards before heading west. The track runs along the southern side of the estate and follows the wine cellars in a slight S-shape. Further on, the track descends gently and passes to the north of a sewage treatment plant. Go straight on across the junction immediately afterwards and continue to the next junction.
(3) Turn left onto a wide track that slopes gently down towards the Jalle du Nord. Cross it via a bridge and walk through a marsh, heading south. Just after a second bridge, the track reaches a T-junction.
(4) Turn left onto the stony track that runs along the southern side of the Chenal du Milieu. In this part of the Marais de Beychevelle, you may come across sheep in movable enclosures, each of which is guarded by a Patou-type dog. Further on, the route reaches the bridge.
(1). Cross the Chenal du Milieu via the bridge and immediately turn right onto the stony track on the northern side of the channel to return to the starting point (S/E).
