Aiguille du Midi (that in english language means Needle of Mid-day) is situated in the Mont Blanc mountain range. The cable car was built to the summit in 1955 and held the title of the world's highest cable car for about two decades. In a spectacular ascent it is possible to travel from Chamonix up to the top of the Aiguille du Midi over 2800m vertical in only about 20 minutes.

A nice way to climb Aiguille du Midi is start from Punta Helbronner (reaching by cablebox from Courmayeur, Italy) and crossing the Glacier du Geànt and the Vallee Blanche (really wonderfull). During this experience (about three hours) you can admire on the left Tour Ronde, Mont Blanc, Mont Maudit and Mont Blanc du Tacul. On the right Dent du Geant and Grandes Jorasses. Be carefull to the sun, the light and the reflex on the ice are very dangerous and you need a very high protection! You can reach also Aiguille du Midi from Chamonix and Cormayeur through Punta Helbronner by cablebox.

The crossed from Aiugulle du Midi to Punta Helbronner about 80 euro and is very panoramic. The cablebox is closed in case of strong wind. No fees are necessary to climb in this region. If you cross by car the Mont Blanc gallery (Chamonix-Courmayeur) you have to pay about 35 Euro. There is also bus service that throughs the tunnel (11 Euro go, 20 euro go and come back, 45 minutes trip).

Mountain Conditions

The best time to climb is between June and September (but in August the crevasses are more than June and September). By skies from December to May (in February is perfect, but depends by the conditions of the glacier, check before to leave!).

Ref. des Cosmiques (3593 m)
The Ref. des Cosmiques is situated on a shoulder between the Col du Midi and the SW-ridge of the Aig. du Midi (Cosmiques-ridge).
according to Eberlein:

    • 140 beds


    • guarded from February till october


  • phone: ++33(0)450544016

Abri Simond Bivouac Hut (3600m)
The Abri Simond Bivouac is situated just a few meters northern of the Ref. des Cosmiques, just at the beginning of the Arête des Cosmiques/South-South-West Ridge to the Aiguille du Midi.

    • 18 beds


    • no fee for staying there overnight


  • open in winter, when Ref. des Cosmiques is closed

The Abri Simond Bivouac hut does not exist anymore "officially", i.e. no current guide book, as far as I know, names this bivouac hut anymore. In an old edition of Eberlein, one could read already about 15 years ago, that this bivouac hut is NOT useable anymore... so it is only insider-knowledge, that this bivuoac hut is open in winter when the Ref. Cosmiques is closed. The true reason (according to insider knowledge) why this bivouac hut still exists and is open in winter (and even the garbage cans of which are removed "officially" by the order of Chamonix or the Ref. Cosmiques) is that mountain guides use this bivouac hut in winter when they bring up their clients for winter ice climbing. Obviously, it is more comfortable for them to stay in the bivouac hut than to camp (although I am myself not totally convinced that the stuffy hut is better than a tent with fresh air if you stay only one or two nights overthere).

Another unconfortable (but cheeper) solution:
Is it also possible to sleep in the cablebox-station of the Aiguille du Midi on the floor, at 3842 meters: is free and many alpinists that climb Mont Blanc, Mont Blanc du Tacul or Mont Maudit do it, but is very important have something against the cold, because the temperature after the sunset is very low!

The Abri Simond Bivouac Hut is not really marked on any current map as fas as I know. On the current french map (3630 OT), there is only written the name "Abri Simond" as summit station of the old material cable car. But the bivouac hut is located just at this point.
