From the Super Lioran resort, take the D67 up to the Col de Cère. 380 m further on, take the small asphalt road on the right to the Col de Font de Cère. Park in one of the two car parks on either side of the road.
(S/E) Walk to the back of the large car park, passing in front of the restaurant.
(1) After passing the restaurant, take the hairpin bend to the left onto the GR®4-GR®400 path, heading north-west. Follow theGR®® markings, alternating between the edge of the ski slope and the path. At the edge of the forest, go through a fence, then climb up to the left of the Rombière chairlift upper station. A few metres further on, leave the GR® on your right and climb up to the left towards the metal barrier.
(2) Go through the gate, continue straight ahead, then climb up the south-western slope below the 1,617 m summit.
The path that branches off to the left along the fence at the gate will be used for the return journey. After curving to the left and then turning right, the path climbs gently to Puy Griou.
(3) Reach the saddle that connects it to the summit of the puy at 1618 m. Go through a gate, then start the ascent on the trail, preferring the paths on the right side of the north-east face of the Puy, which is in front of you.
Then, via a sustained climb through phonolitic rock formations, where you will need to use your hands in places, reach the summit adorned with its cairn.
(4) Descend to the saddle. Climb back up the well-marked path that runs along the fence to the summit of the hill at an altitude of 1,618 metres.
(5) Follow this path, descending gently to the north-east until you reach a metal gate.
(6) After passing it, descend on the path to the north-west.
(2) Take the same route back to the car park (S/E).
; I recommend taking the few paths that go around it instead.
