Park at the Parking des Barnets car park on the road leading up to La Sierre station. Choose the lower section, with angled parking spaces.
(S/E) Cross the road at the "Site de Vol Libre de l'Aigle" signs and take the gravel track that descends northwards. Immediately on the left, about twenty metres away, you will see a path, which is not very visible at first but is well marked, climbing steadily at a gentle gradient.
Follow it until you reach a bend in the forest road.
(1) Go around the bend and take a path that zigzags up the slope. There are several tracks, but stay on the one that is well marked by mountain bikes.
When you come to a forest road at a bend, cut across the bend and follow the path that climbs up to the ridge. You will arrive at the Croix des Suifs.
(2) Continue straight ahead on the ridge. After a descent, you will arrive at a small pass with little vegetation. Do not head towards La Salière.
Turn slightly left to descend towards La Sierre. You will arrive at a beautiful track on the pass, which you should follow south for about 200 metres.
(3) Look for a goodGR® marked trail parallel to the track. Join it and follow it. It leads directly to the Col de l'Arc. Very beautiful panorama, comfortable for a break.
(4) Turn left, heading north-northeast, onto theGR® towards Pic Saint-Michel. Continue to the crossroads at the foot of the peak (signpost).
(5) Climb a few metres to the cross at the summit and enjoy the magnificent 360° panorama. Then begin the descent, which is a little steep in places and crosses areas of sharp limestone pavement that can be slippery, with quite a few tracks, between which you may hesitate.
I chose to follow intermittent yellow-green markings, only to realise that I had ended up taking a "shortcut" compared to the usual recommended routes.
=> This is a region with a sharp limestone pavement, so be careful, but if you follow the tracks, you'll get through without any difficulty. It is essential to stay on the well-marked tracks: if in doubt, go back up to find the lost track. You will arrive at a stony track.
(6) Cross it to take the path/trail opposite in the pasture to the north, which leads back to the car park (S/E) following the bottom of the Combe Claire.
