From Pont-de-Pany, head to Agey (21) via the D 108. At the first junction at the village entrance, turn left onto Rue du Patis to park a few metres further down in the car park behind the town hall.
(S/E) From the car park, walk down Rue du Patis to the crossroads. Turn left to walk down to the castle via the D 9g. Rue du Château continues as Rue des Brosses. Just past the joinery, turn right onto a gravelled track suitable for vehicles.
(1) Follow this track as it climbs through fields and meadows to the edge of the forest. At the edge of the woods, on the right, hidden beneath the trees, is the first cabotte (dry-stone shelter). Immediately after, at the fork, take the path on the left (signposted ‘champ guide’ to the left). Pass a second cabotte on the left of the route and, at the next crossroads, keep to the right.
(2) Walk past the hunting lodge “La Conservatrice”. Continue along the stony path to the first fork. Turn right. 40 metres further on, at the second fork, take the left-hand path. Beautiful woodland with a dry stone wall to the right. Continue along the same path, ignoring the side tracks. It climbs steadily before becoming very steep shortly after a hunting post. When you reach a dead end at a cross path, turn left (uphill).
(3) Follow this same path, ignoring any side branches. It makes a wide bend to the right just after a crossroads where there is a blue sign reading “Barbirey hunting area”. Continue along the path to a crossroads at the top of a hillock. The number 5 is painted in orange on a tree, facing you. Turn left.
(4) Head down the clearly marked, winding path, using the stone wall on your right as a guide. It widens and joins a large crossroads of tracks. Turn left.
(5) Follow the stony path down to the next junction. Turn right towards the Roche-Chèvre Cave (yellow sign indicating 400 m). At the top of the climb, when you reach a crossroads of tracks, turn left. A signpost indicates the direction of the cave (100 m). Descend through the scree to reach this remarkable cave.
(6) Access to the cave is prohibited as it is home to protected bats, a species that must be preserved.
Continue down the steep slope along the same path. When you reach a crossroads, head up the track to the left and then take the first path on the right (marked in white). This leads successively to the cellar, past two cadoles, and on to a stone cairn.
(7) After going round the cairn, take the path further up despite the White Cross painted at its junction. It winds through the woods, passes through the ruins of an old village and leads to the remains of La Casquette. Head down the path to Barbirey. Turn right.
(8) Head back up the open path straight ahead. It forms several circular patterns before reaching a crossroads of tracks (cherry trees on the left). Stay in the undergrowth and follow the purple markings. At the next crossroads, leave the purple markings and turn left onto a path marked in white.
(9) It winds halfway up the hillside through the woods then passes at the foot of rock faces (guide on the right). It leads, via ascents and descents, successively to “la Roche Belle”, “la Roche Fendue”, the Source du Rouleau and the Cave du Marquis before reaching the “Trou-qui-fume” cave. Descend to the path visible 20 m below. Turn right.
(10) Follow this track until you reach the tarmac road of La Montagne. Turn left to go down it. When you reach the junction of Chemin des Vignes and Rue de la Fontaine (in the commune of Grenant-Les-Sombernon), head right up the tarmac road of Les Vignes.
(11) It becomes a dirt track. At the next junction, keep to the right to continue climbing between two rows of trees, until you reach a five-way junction near the hamlet of La Montagne. Head due west.
(12) The road continues from the one coming from Vaux-Les-Grenant. Head straight towards the modern house with a turret, situated at the junction with the D 114m. At this junction, turn right. Further on, at a sharp left-hand bend, leave the D 114m and turn right onto a tarmac road leading to the PC 541 water reservoir. Keep to the right and continue along a dirt track through the fields. At the first junction, at the edge of the woodland, turn left. At the second four-way junction, take the left-hand fork.
(13) Continue along this route without taking any side paths. Shortly after it becomes tarmac, at the next junction, leave it and head straight down a stony track. View of the village of Remilly-en-Montagne below. At the junction with the D 108, turn right to walk past the restored old mill whilst following the D 108 towards Sombernon.
(14) At the next crossroads, take the path opposite, at the foot of the rocks. This leads to Rue de la Creuse, which heads right towards the church. Take the first right, Rue des Poils Blancs, then head down Rue de l’Église. Cross right through the old village, passing in front of the town hall and heading up to the left along the Grande Rue, which becomes a dead end. You will arrive at a wayside cross erected on 1 October 1848 by a civil ‘engineer’ (according to the inscription). Head straight ahead down the stony path. Further on, it turns into a track separating woods and meadows. Vineyards are present. Upon reaching the iron cross at Les Torrents (boxwood on the right), at control point 364, head down to the right.
(15) Follow this path to the stone cross at Molphey, at the junction with the D108, at the entrance to Agey. Cross “la Sirène” to the right via the bridge. Immediately afterwards, turn left onto Chemin des Ruelles and then, further on, keep left onto Rue des Riots. This will take you to Rue du Château. Walk up this street, passing the building once more, to reach Rue du Patis and the car park (S/E).
