Head to the village of Saint-Étienne-de-Tinée. Park in the car park near the Mercantour Park Visitor Centre.
(S) Leave the car park, head towards the Tinée, cross the bridge and head for marker 100, which is clearly visible after the bridge (signposted: Chemin de l’Énergie, Rabuons Mountain Hut and Rabuons Lake).
(1) At marker 100, turn left onto the path that runs alongside a stone wall. Continue through a deciduous forest until you reach marker 101.
(2) Turn right towards Rabuons. Continue up the winding path through a larch forest until you reach marker 102.
(3) Continue to the right along the path, which continues to wind its way up a fairly steep slope. At the 2250 mark, the forest thins out. Carry on to reach the treeless summit of the ridge and marker 103, which is very close by.
(4) Turn right towards the Rabuons mountain refuge. Follow the wide path known as the “de l’Énergie”, which is almost flat. You will reach marker 104.
(5) Head east, still towards Rabuons, pass the EDF building and continue along the wide path to marker 105.
(6) Cross a small bridge and climb up to the Rabuons mountain refuge, which is now clearly visible (E).
