Téléphérique de l'Aiguille du Midi
As described under 'tourism', this is the primary high-alpine lift in the valley, a two-stage cable car (Plan de l'Aiguille at 2,310m, then Aiguille du Midi at 3,842m). It has a very high capacity, transporting thousands of visitors daily. Essential for access to high-altitude mountaineering, off-piste skiing, and sightseeing. The second stage has a vertical rise of over 1,500m.
