Bec de l'Aigle, Mountain summit in Cantal, France

Bec de l'Aigle is a 1,699-metre summit in the eastern part of the Cantal stratovolcano, in the Alagnon valley on the commune of Laveissière. It is built from stacked trachyandesitic lava flows that appear here as breccias. Like a ship's prow it overlooks the Font d'Alagnon glacial cirque to the west and the Alagnon glacial valley to the east.

Bec de l'Aigle is a stack of trachyandesitic lava flows from the Cantal stratovolcano's violent eruptive phases between 8.5 and 6.5 million years ago. At this summit the flows appear as breccias, fragments of lava and rock cemented together. It stands in the eastern part of the stratovolcano, above the Font d'Alagnon glacial cirque to the west and the Alagnon glacial valley to the east.

The name Bec de l'Aigle, "eagle's beak", comes from the shape of the rock, which resembles a bird's beak. The summit stands above the Font d'Alagnon glacial cirque to the west and the Alagnon glacial valley to the east, which runs down to Murat. With the neighbouring Rocher de Redon it frames the Vassivière hollow, which ends in front of the Puy de Seycheuse.

The GR 400 hiking trail offers the most accessible route to reach the summit, while the path from Font d'Alagnon requires more effort and passes through denser forests. Hikers should prepare for changing weather conditions and wear sturdy footwear.

Several streams originate from the mountain's slopes, including La Croix, Loubaleyre, Chavagnac, and La Grange, which feed into the Alagnon Valley water system. These sources form the starting point for a network of watercourses that support the surrounding ecosystems.
