Take the Col d'Izoard road and park in the large field at the exit of Laus de Cervières (in the direction of Briançon - Izoard).
(S/E) Cross the road and continue towards the woods until you reach the trail. Turn right, pass under the arch formed by the two electricity pylons, then join the Sentier Botanique crossroads.
(1) Take it to the left (Botanical Trail sign) and follow thePR® (yellow) markings, which will take you almost to the end. A series of hairpin bends will take you to a forest road. Take it to the left for about ten metres, then turn right onto the parallel path (sign). Stay on the hillside to reach a new crossroads.
(2) Start a steep climb on the right. You will then reach a shoulder and, on the left, the almost horizontal path that leads to the Col d'Izoard road.
(3) There are no morePR® markings here, so head straight ahead and descend into the meadows. When you reach a wide track, turn right and follow the road until you reach a bend on the right.
(4) Take the track opposite (signposted Fort de la Lausette): it is marked in yellow again.
Pass the ruined chalets and bear right to join the clearly visible path opposite. Stay on this path; the yellow markings on the stones and trees lead to the crossroads known as Les Loubatières.
(5) Then turn right onto the path that descends steeply into the woods. The numerous hairpin bends end on the Col d'Izoard road. Take this road to the left for about 100 metres to return to the car park (S/E).
