(S/E) Follow the D77a road to join the main D9 road linking Vesoul to Villersexel.
(1) Cross this road carefully and head off to the right. Walk for about 150m then enter the woods on the left. Follow the path until you reach the Chemin Vert (or Voie Verte)
(2) Turn left and after about 250m (past the boulders), take the small winding path on the left to descend to a valley. Head left again to reach the end of the valley and arrive at the Frais Puits chasm.
(3) Set off again along a path that starts at the corner of the chasm’s fence and rejoin the path taken to reach the Chemin Vert. Turn left.
(2) This time, head right and continue along this path for 4.5 to 5 km. Cross the road leading to Villers-le-Sec.
(4) Cross the D76 and continue straight on until you reach a yellow and grey bridge (signposted Saint-Igny).
(5) Cross the bridge and go down the steps on the left to pass under the bridge. Head towards the hamlet of Les Belles Baraques.
(6) Carefully cross the main road (D9) again and continue straight ahead along the tarmac road. You will then pass through several hamlets (Les Marcassins and Grange Mercier) before reaching the D76.
(7) Take this road to the left and leave it 80m further on by turning right to reach the Belle Côte farm. Continue along the road up a lovely climb that passes close to numerous horse paddocks. Leave the path leading to the hamlet of Les Charbonniers on your left.
(8) Ignore the access road to the hamlet of Les Guinguettes and head straight on to the Château Bleu farm.
(9) Continue straight on to reach the junction with the Vesoul–Villersexel road you took at the start.
