Aiguille du Fou

Aiguille du Fou is a peak in the Mont Blanc massif standing around 3500 meters high within the Aiguilles de Chamonix group. The mountain consists of sharp granite spires that rise steeply above the surrounding glaciers and rock faces.

The first ascent occurred in 1901 when climbers E. Fontaine and J. Ravanel reached the summit, opening new possibilities for mountaineering in the area. A major climbing route on the south face was established later in the 1960s and remains one of the most demanding challenges.

The name translates to 'Needle of the Madman', describing how locals and climbers refer to the sharp, difficult granite formations. This name reflects the reputation this peak has built among mountaineers for its serious climbing demands.

The best route involves taking the Montenvers Train and then crossing a glacier with technical sections using fixed ropes and safety gear. Climbers should expect glacier travel with variable conditions and the need for proper precautions throughout the approach.

The peak stands out for its contrasts between smooth ice and vertical granite pillars that rise side by side. This unusual combination creates a striking visual that reveals the extreme conditions climbers must handle.
