Exploration and Mountaineering
18th century : The Alps become a playground for scientific exploration and mountaineering. The Mont Blanc massif quickly draws attention.
1818 : First recorded ascent of the Aiguille du Midi by Antoni Malczewski, accompanied by Chamonix mountain guides.
The Aiguille du Midi soon becomes a key objective for climbers thanks to its gateway to high-altitude terrain.
The Birth of the Cable Car
1909 : The idea is born to build a cable car linking Chamonix to the Aiguille du Midi.
1924–1927 : Construction of a first section up to the Plan de l’Aiguille (2,317 m).
1951–1955 : Construction of the current cable car — a remarkable engineering feat for its time.
At the time of its completion, it became the highest cable car in the world. The official inauguration took place in 1955.
Modern Developments
1991 : Opening of the elevator to the summit terrace, offering a 360° panoramic view.
2013 : Launch of the attraction "Step into the Void", a glass box suspended over the abyss.
2015 : Opening of the Espace Vertical, an exhibition space dedicated to the history of mountaineering and the Mont Blanc massif.
Breathtaking Panoramas
Panoramic Terraces : Enjoy a 360° view over the French, Swiss, and Italian Alps — including Mont Blanc, the Grandes Jorasses, the Matterhorn, Monte Rosa, and more.
Summit Terrace : Accessible via elevator, this is the highest point of your visit — and the ultimate viewing platform.
A glass box suspended above a 1,000-meter drop.
Guaranteed thrills for those who dare — perfect for unforgettable (and vertigo-inducing) photos!

Espace Histoire : A retrospective exhibition on the construction of the cable car — complete with views of the impressive machinery that powers it.
Hypoxia Zone : Learn about the effects of reduced oxygen at altitude on the human body — an insightful (and sometimes surprising) stop.
Traverse to Pointe Helbronner (Italy)
Panoramic Mont-Blanc Gondola (summer only) : Float across the glaciers of the Vallée Blanche to Pointe Helbronner on the Italian side. A spectacular aerial journey above crevasses and iconic peaks.
