(2) Take the second lane on the left at a 90° angle, the Route de la Rachée. After about a hundred metres, leave this road and turn right onto a bridle path running along the boundary between the state-owned forest and private woodland. Stay close to the embankment and the ditch marking the forest boundary; do not cross them.
(3) Further on, the path turns eastwards and remains within the state-owned forest.
(4) You’ll come out onto a tarmac forest road; follow it to the left. Immediately cross the Rond de la Rachée and continue along the tarmac. Pass the Chêne d’Hérissé, a remarkable oak tree that towers above the others, and carry on for another hundred metres.
(5) Then turn right onto the track between plots no. 143 and no. 144.
(6) At the end, turn left and follow a stream (not shown on the map). Ignore a path on the left (plots nos. 143 and 142) and head for the Ligne du Haut Cornet.
(7) Turn left and you will soon reach the Grand Rond (S/E).
