Park in the car park at the Barbirey-sur-Ouche Town Hall, 21410
(S/E) Cross the town hall square and walk past the washhouse and drinking trough, listed as a “Remarkable Monument”.
(1) Turn right into Rue de Jaugey. Follow this road, then Rue des Lurots, until you reach the Chamboran Bridge over the Gironde. A sign points towards “Tour Denis Gaulard – Saint-Victor via Ruère”; follow the yellow markers.
(2) Head west onto the D114. After about 300 metres, turn left onto a track that crosses a large field, before climbing along the edge of the woods to the crossroads marked by a sign reading: “Viewpoint 500m – La Table du Druide”.
(3) Leave the yellow markings and continue by following the white markings of the “Tour de Barbaricum”, which passes through La Table du Druide. The path continues along a ledge before turning right onto a track heading south. After about 150 m, this leads to a stony track. Turn left onto this track. It heads east, initially on level ground for 300 m, then descends steeply in hairpin bends.
(4) After 400 m, leave the white markings for the “Tour de Barbaricum”. Turn right onto the path that climbs southwards for about 800 m to reach the ruins of Marigny Castle.
(5) Enter the enclosure without ever straying from the narrow path worn by foot traffic. It is dangerous to venture elsewhere. Exit via the gatehouse and follow the path heading north-west before turning west to reach a crossroads.
(6) Turn left onto the stony track until you reach the junction of the two towers: Marigny and Denis Gaulard, north of the hamlet of Auvillard.
(7) Turn left. From here, follow the yellow markers to the finish. Cross the D33 road in Auvillard to reach the stone bridge over the Ouche and cross it.
(8) When you reach the Burgundy Canal, turn left onto the old towpath. Follow it for 2 km to the bridge over the D8 road.
(9) Turn left onto the D8 and follow it for about a hundred metres. In front of the picnic area, turn right onto the stony track. This will cross the D33 before crossing a very old, narrow stone bridge over the Gironde. The return to the town hall grounds is via the dry-stone wall in the castle grounds. Before the wash house, cross the town hall square to reach the car park (E)
