Access by car is via the forest road that leaves from the hamlet of Les Payas in the municipality of Pellafol towards the Col des Faïsses. Take this road as far as you can, several kilometres above the hamlet of Les Payas. Park in the car park (it is easy to pitch a tent here if you arrive the day before).
(S/E) From the car park, follow the forest track towards Col des Faïsses, leave the first path on your right at the end of the car park, then take the first path on the right 100m higher (after a barbed wire fence on the right).
(1) Follow the path until you reach the ridge, then follow the ridge path towards Obiou.
From here, the path is marked with red lines. Follow the markings and reach the Pas du Vallon.
(2) Follow the main trail until you reach a fork where it splits into two.
(3) Turn right, following the red markings. You will reach a relatively steep scree slope.
(4) Continue to follow the red markings. (It is sometimes useful to use your hands in certain steep sections. I strongly advise you to wear a helmet from this point onwards, as small stones falling from hikers above are very common). You will reach a crossroads below the Tête de l'Obiou.
(5) Continue climbing, following the red markings. Join a path.
(6) If you turn left, you can reach a cave about a hundred metres further on (the cave is open to visitors; take a head torch to admire the magnificent ice wall at the end of a small passage on the left of the main cave). Return to the main trail via the same path. I recommend visiting the cave on the way down so as not to break your rhythm on the way up.
Continue along the red marked trail to reach the pass.
(7) Turn right, following the ridge path, then join the trail that passes through the ledge on the left (red markings).
(8) Follow the red markings on the rock to the summit of Obiou. Small passages in the rock require you to use your hands. Take great care if the ground is slippery, as there is a significant drop in this area and sure footing is essential. Remember to keep your helmet on in case of falling rocks along this section. Reach the summit of Obiou.
(9) Enjoy the magnificent 360-degree panorama, then after a well-deserved break, descend via the same route. Stay alert, keep your footing and watch out for falling rocks on the way back. Return to the junction of the loop.
(5) It is best to return to the right via the scree (clearly visible trail) to rejoin the original path.
(3) Follow the same route back to the car park (S/E).
