- When you reach a flat spot on the same path, continue straight on for about 700 m.
- Pass a large stone milestone on the left (with the Mac Mahon crest), then go straight on and take the next goose foot on the left.
- At the crossroads, go straight on and come to a stony track, turn right (1.5 km through the stones).
- Pass a blue lorry and follow the track to the forest road (tarmac). Turn right and follow it for about 3 km to the TGV bridge.
- You will return to the starting point.
