Car park at the Flagey farm, former property of Gustave Courbet's family. Yellow-blue markings.
(S/E) Leave the car park at the back of the farm towards the village. In the Grande Rue, turn left towards the church. You will pass the ox shoeing apparatus. Then turn right before the church into Rue de Bonneille. Head towards the Ruins of the Mill. Continue along the dead-end road.
(1) At the village exit, the street splits into three; take the middle path. This is Chemin du Moulin de Bonneille, which quickly becomes stony and passes a small astronomical observatory, somewhat incongruous in our Comtois countryside.
(2) At the bottom, the road levels out. Look for a small footbridge on the right that crosses the stream. Continue straight ahead for about 200 metres to catch a glimpse of the small valley and a small waterfall. Return to the footbridge and cross it. Immediately after (forest sign no. 5), at the rocks, climb the path that ascends diagonally to the right. At the wider path, continue to the right. At the gravel road, descend to the left for about 150 metres until you reach the entrance to a fir forest. Leave the road and climb to the right into the woods, heading towards Vieux Chêne de Silley.
(3) You will arrive at the magnificent old oak tree, which resembles the one painted by Gustave Courbet. Turn your back on the tree and set off again along the path. You will come to a wider path, which you should take on the left. At the Silley forest signs nos. 19 and 18, take the path that climbs up into the fir forest on the right. Cross a gravel road and continue along the forest path opposite. At sign no. 16, you will come to a semi-gravel path; take it on the left.
(4) You will pass a remarkable beech tree. Picnic table. A little further on, at the fork, continue to the right. At the pasture, follow the edge on your left to find a gravel path that will take you to the first houses of Chantrans.
(5) Turn left and then left again at the wooden cross, passing in front of the church to discover the 19th-century fountain and wash house.
(6) After the fountain, climb a few metres to the right, then immediately right to the old weather-beaten calvary. With your back to the calvary, turn left into Rue de l'Église. At the small square on the left, you will see a medieval fortified farm with a square turret. Then return to the intersection you passed on the way to Chantrans, via Rue de l'Église and Rue des Tilleuls.
(5) Turn left and leave Chantrans via Chemin de Tannière. The path becomes stony, then turns into a simple field path.
(7) Cross the stony road and continue straight ahead into the field opposite. Do the same at the next stony path, following the barbed wire fence. Continue straight ahead through the copse towards a zigzag passage in the fence. You will find yourself on a more distinct path. Cross the Bonneille stream again via a wooden footbridge, climbing a wooded hill via steps.
(8) At the top, walk along a sparse pine forest on your left for about 50 metres and then veer slightly to the right towards Ferme de Flagey, taking the path that climbs into the copse. When you reach the fence, cross the pasture and find another passage on the other side. At the first houses in Flagey, take the small path at the right-hand corner of the tennis court. You will find the path you started on, which you take to the left until you reach the church, then left again to return to the farm car park (S/E).
