Téléphérique de l'Aiguille du Midi, Alpine aerial tramway in Chamonix-Mont-Blanc, France

The Téléphérique de l'Aiguille du Midi is an aerial cable car that connects Chamonix with the summit station at 3,842 meters elevation and spans 5,420 meters of distance. The ascent uses two separate sections with an intermediate stop at Plan de l'Aiguille station and takes approximately 20 minutes to reach the top.

The first section from Chamonix to Plan de l'Aiguille opened in 1954, and the second section to the summit station at 3,777 meters opened in 1955. At its opening it was the highest cable car in the world. It is operated by the Compagnie du Mont-Blanc, which also runs most other lifts in the region.

The name Aiguille du Midi means "Needle of Noon" in French, referring to the sharp peak. The cable car's upper section climbs at 47° near the top, and since December 2013 visitors can step into a glass box called Pas dans le vide, mounted on the summit terraces. The Compagnie du Mont-Blanc, which runs the lift, also operates most other cable cars and rack railways in the region.

The first section reaches Plan de l'Aiguille in 6 to 8 minutes; from there, marked paths lead to Lac Bleu in about 15 minutes or on the 2h30 Balcon walk to Montenvers, and hikers can also descend all the way to Chamonix. At the top, a footbridge links the northern and central peaks, and a lift climbs 66 m to the 3,842 m summit. From the summit, the Panoramic Mont-Blanc cable car crosses the Géant Glacier to Pointe Helbronner (3,462 m) in Italy in over 20 minutes.

The signature attraction is the Step into the Void, a walking glass cube that appears to float freely over the mountain slopes below. Visitors can stand 1,035 meters (3,400 feet) above the terrain and look down at the landscape beneath their feet.
