Gouffre des Busserailles

The Gouffre des Busserailles is a pit cave in Valtournenche carved by a mountain torrent that continues to flow through its interior. The rock walls have been smoothed and shaped by water action, creating a narrow passage that descends steeply into the mountain.

Local alpine guides explored and opened this cave to visitors in the mid-1800s, establishing it as a destination for those interested in mountain geology. Since then it has remained accessible to the public as a natural attraction.

The Maquignaz family maintains responsibility for cave management since its initial exploration, preserving this natural formation for generations of visitors.

Wear sturdy footwear and bring warm clothing since the interior stays damp and cool year-round. You will need a flashlight or headlamp to safely navigate the passages and see the rock formations clearly.

Natural stone bridges have formed where the flowing water has carved away the rock beneath them, creating distinctive geological structures. These formations show how powerful water erosion can be in shaping the cave over time.
