From Arêches le Planay, head for Le Chornais and park near the holiday centre.
(S/E) From the car park, climb the tarmac road for 150 m to its end, then continue along a wide track that descends slightly to reach the Quéfins mountain pasture.
(1) Follow the signpost and climb up to the left into the forest via a winding path. This emerges in the mountain pasture, below a wooden barn. Continue climbing up the mountain pasture, then continue climbing after passing two farm buildings until you reach an intersection (signpost for Les Combettes 1,792 m) with theGRP® Tour du Beaufortain.
(2) Leave the path to the right towards the Refuge des Arolles and continue left towards Lac Tournant until you reach the next intersection (signpost for Entre le Fer 1943 m).
(3) Leave theGRP® here and take the path on the right that leads to Lac de Brassa.
(4) After the lake, continue climbing towards a pass. The path will lead you to the arrival station of the Combettes chairlift.
(5) Descend via the ski slope to pass under the Grande Combe ski lift. The Refuge des Arolles is clearly visible and can be reached via the stony slope, but it is better to take the path on the left side of the valley. Shortly before arriving at the refuge, rejoin the GRP®.
(6) From the refuge (signpost), descend along the path towards Le Chornais, which crosses a track several times. Pay close attention to the markings (yellow) or you may end up in Le Planay. The path rejoins the forest for a long descent and finally leads to the Quéfins mountain pasture.
(1) Take the same route back up to Chornais (S/E).
