Aiguille du Midi in the context of "Mont Blanc massif"

Chamonix-Mont-Blanc (French pronunciation: [ʃamɔni mɔ̃ blɑ̃]; Arpitan: Chamôni-Mont-Blanc; Italian: Sciamonìcode: ita promoted to code: it (no longer in use)), more commonly known simply as Chamonix (Chamôni), is a commune in the Haute-Savoie department in the Auvergne-Rhône-Alpes region in Southeastern France. It was the site of the first Winter Olympics, held in 1924.

Chamonix is situated in the French Alps just north of Mont Blanc, the highest mountain in Western Europe. Between the peaks of the Aiguilles Rouges and the notable Aiguille du Midi, it borders both Switzerland and Italy. It is one of the oldest ski resorts in France, popular with alpinists and mountain enthusiasts. Via the cable car lift to the Aiguille du Midi it is possible to access the off-piste ski run of the Vallée Blanche ('white valley').

The Vallée Blanche Cable Car (Italian: Funivia dei Ghiacciai; French: Télécabine Panoramic Mont-Blanc, previously Télécabine de la Vallée Blanche) is a passenger cable car linking a mountain peak above Courmayeur (Italy) to a peak above Chamonix (France) by passing over the Mont Blanc massif, in the Alps. The engineering was developed by Vittorio Zignoli of Polytechnic University of Turin. No helicopters were used, and all the workers were chosen among locals and alpine guides. After a construction period of four years, it began service in 1958.

The cable car connects the peaks of Aiguille du Midi (3,778 m (12,395 ft) elevation) and Pointe Helbronner (3,466 m (11,371 ft) elevation), over a distance of some 5 km (3.1 mi). The two peaks have their own cable car system connecting them to their nearby villages. The French Téléphérique de l'Aiguille du Midi connects the peak of Aiguille du Midi to the village of Chamonix, while the Italian Skyway Monte Bianco (Funivie Monte Bianco) connects the peak of Pointe Helbronner to the village of La Palud, just north of Courmayeur.
