with each other over a distance of some 5 km (3.1 mi).

It has fixed track cables (one each direction) carrying 12 groups of 3 small cabins each which are pulled by a haulage rope of 10200 m (33,464.6 ft) in a single loop.

The cabins take some 30 to 35 minutes for the whole distance including 5 short stops corresponding the stops of the cabins in the stations at either end.

The cabins run from the Aiguille du Midi station (3778 m (12,395 ft)) over a stretch of 1,684 metres (1 mile) to the Gros Rognon station (3536 m (11,601 ft)), whereby it crosses the Vallée Blanche, a glacier and snow valley. The Gros Rognon station is purely technical, it contains the counterweights of the fixed cables and the rails bending the horizontal direction of the cables by some 8° to the right.

Behind the Gros Rognon it crosses the glacier
Glacier
A glacier is a large persistent body of ice that forms where the accumulation of snow exceeds its ablation over many years, often centuries. At least 0.1 km² in area and 50 m thick, but often much larger, a glacier slowly deforms and flows due to stresses induced by its weight...

 Glacier du Géant and spans a length of 2,831 metres (1.76 miles) without support. Although the cables sag by some 255 m (836.6 ft), the cabins still have a clearance of some 300 m (984.3 ft) to the glacier underneath.

Between the rocks of the Large and the Small Flambeau three 315 m (1,033.5 ft) long steel cables are installed, which take over the role of the cable support (Pylône suspendu / Suspended Support Pillar). During construction, it was decided to build this unique configuration, because the glacier is unsuitable as the location of high tower construction. Between the anchors of these cables at either side, there is a difference in altitude of 136 m (446.2 ft) and furthermore, these cables have a horizontal inclination of some 23 ° to the direction of the tramway.

From this support the aerial tramway runs to the Pointe Helbronner, also at 3466 m (11,371.4 ft), again with a span of 447 m (1,466.5 ft).
