Rockfax Description
I, 100m, 1 - 2 hours. An excellent, short climb which lacks technical difficulties but not exposure.
Approach - Descend the Aiguille du Midi via the famous snow ridge before swinging around west and passing under the Midi South Face, Arête des Cosmiques and Refuge des Cosmiques to reach the foot of the route.
1) The ridge can be joined almost anywhere within 100m of the Col du Midi, but the most enjoyable scrambling is found by starting in a small snow bay just to the left of where the rock solidifies considerably.
2) Climb leftwards up a ramp before turning right and following the ridge on its crest, turning difficulties on the left.
3) 4b. Halfway to the refuge there is an awkward slab which can either downclimbed (4b) or abseiled (5m). From the foot of the slab, return to the ridge crest and continue along the ridge in a stunning position to reach the terrace at the back of the Refuge des Cosmiques.
Descent - Return to the Aiguille du Midi. © Rockfax

UKC Logbook Description
Not sure of grade-possibly AD-. The alternative route if weather is too bad to do Cosmiques Ridge. Starts from Col du Midi (3532m). As you walk away from aiguille du midi turn right to approach the ridge running south west of cosmiques hut (3817m). Mixed scramble and easy climbing but very exposed climbing across l'arete a laurence. Whole route very exposed with a particularly scary traverse near the end probably best done with some protection. A ladder at the end of the route takes you in to the back entrance of the cosmiques hut.

UPDATE: Large loose block (small lorry size) that is waiting to go down the north face near the hut end, the route traverses over the block. Would easily cut rope/slings if used for protection. Could be avoided by a very dangerous scree traverse below the block.

With icicle mountaineering. Terrible weather, strong winds and snow but at least it was warm in the hut.

Mr Fuller 09/Jul/16 AltLd O/S

Nice little route, some good positions. This is nowhere near AD though and more like Facile... very short, easy descent, next to a hut, quick access, not very high, requires use of hands on very little of the ridge, good opportunities for protection. Either way, it's a great route.

Moved together then pitched the downward traverse. Cosmiques hut was closed so we had to reverse the route and run across the col and back up the arête du midi to catch the last cable car. Very tiring as it was only our second day at altitude.

JenShelley 29/Dec/15 -

Did this twice! Once south to north, moving together for all but the traverse near the end. Got to the platform at the Cosmiques Refuge, and the door was locked and no other way off the platform! So had to do the route again north to south in double quick time then race across the Col du Midi to avoid missing the last cable car.

Climbed route during Conville Course (our guide was Dave). Moved together for most of it. Rock traverse towards the end required a bit of belaying. Had half of an 8 omelette in the Cosmique hut afterwards, which didn't stay down due to altitude sickness.

Very snowy, very easy going for the most part with the odd 'move'. Exposure is fantastic in sections. Especially as snow bridges had formed between the boulders leading to my second post holing into space more than once.

No snow at all. Just a scramble. Did an awkward abseil down the slab traverse.
