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 La Tinée, cross the bridge and go to marker 100, clearly visible after the bridge (signs: Chemin de l'Énergie, Refuge de Rabuons and Lac de Rabuons).
(1) At marker 100, follow the path on the left that runs alongside a stone wall. Continue through a deciduous forest to marker 101.
(2) Turn right towards Rabuons. Continue climbing the winding path through a larch forest until you reach marker 102.
(3) Continue on the right on the path, which continues to wind upwards at a fairly steep gradient. At an altitude of 2,250 metres, the forest thins out. Continue to reach the treeless summit of the ridge and marker 103 nearby.
(4) Turn right towards the Rabuons refuge. Continue along the wide path known as "de l'Énergie", which is almost flat. Reach marker 104.
(5) Head east, still towards Rabuons, pass the EDF house and continue along the wide path to marker 105.
(6) Cross a small bridge and climb up to the Rabuons refuge, which is now clearly visible (E).
