Departure from the Col de Plan Bois.
(S/E) From the car park, take the tarmac road eastwards (towards Manigod) and follow it for about 500 metres.
(1) Turn right onto the wide track towards Sous Sulens, Les Crêtets and follow the signs for 'Tour du Sulens'.
Follow this track for about 2.5 km and after a few bends, you will come to a relatively flat section with the grassy face of Sulens on your right. At the foot of this, the meadow is dotted with rocks. About 300 m away is the Bois Noir chalet.
(2) Leave the track on the right and head north. Look for the trail (not very visible) but marked by cairns. Update 2020: signposts have been installed at this point - Sentier du Facteur, Croix de Sulens: follow them.
As you approach the slope, the Sentier du Curé has been cleared and is now well marked. It climbs in a zigzag pattern and leads to the summit ridge. Stay on the ridge (heading south-west).
(3) Pass the Croix de Sulens (1,828 m). Continue south on the ridge to reach the orientation table (1,839 m).
(4) The hike continues along the ridge to a small flat area.
(5) Take the dirt track on the right towards the Sulens chalets.
(6) After the chalets, the track widens and leads directly to the Plan Bois car park (S/E).
