Grotte du Cul de Bœuf

Grotte du Cul de Bœuf is a cave entrance on the slopes of Grand Coyer mountain where different geological layers meet. The cave system extends deep underground through multiple chambers and leads to an underground water body.

The cave was first documented in the 17th century when a scholar sent a physician to investigate the cold winds emerging from the mountain. Later archaeological expeditions discovered artifacts within its chambers.

The name references past farming practices in the region. Visitors today notice the practical access points that successive generations of explorers have used.

The cave entrance sits on a steep mountain slope and requires caution when accessing it. Visitors should prepare for slippery ground and moderate physical demands while exploring.

The cave produces a striking natural phenomenon where wind emerges at sunset and strengthens until midnight. This behavior results from temperature differences between the cave and outside air.
