From the D900, enter Le Vernet and continue until you see the sign for Col de Mariaud and Les Béliers. Follow this road for 2.5 km until you reach a clearing with a sign saying "Parking obligatoire" (parking required). This is where you should leave your vehicle.
(S/E) Start on the gently sloping road.
(1) At this fork, take the path on the left, stay on this path, and you will arrive at Col de Mariaud.
(2) Turn right towards the grey gate, go through it, and gently descend the road until you reach a platform.
(3) Turn left to descend the road, which will take you to a crossroads.
(4) There are two options:
- turn left to go directly to the Col de Mariaud via the fairly steep path.
- stay right and continue downhill, then take the path on the left that climbs towards the sphere.
You will arrive at the gate protecting the sphere, which prevents you from going any further.
(5) You will return to the previous crossroads.
(4) Take the steep path on the right and finish the climb to the Col de Mariaud.
(2) Retrace your steps back to the mandatory car park (S/E).
