Dent de Perroc, Mountain peak in Valais, Switzerland
Dent de Perroc is a peak in the Pennine Alps that rises to 3,676 meters with steep rock walls and a marked west ridge running along its structure. The sharp slopes and rocky surfaces create a distinctive form that dominates the view from Arolla Valley below.
Mountaineers began exploring and documenting routes to the summit during the late 19th century expansion of Alpine climbing. This period saw the start of systematic ascents and route mapping in this region of the Pennine Alps.
The name comes from the local dialect, where 'perroc' means tooth-like shape and reflects the way people in Valais speak about their mountains. Climbers and hikers recognize this distinctive silhouette as soon as they enter the valley.
The route starts from Arolla village and leads to Cabane de la Tsa, from which technical climbing sections begin. Rope and climbing gear are required, and climbers need experience on steep rock faces.
The location between Arolla Valley and Mont Miné Glacier creates different weather conditions on the mountain's various faces throughout the year. This positioning shapes climbing conditions in ways that experienced mountaineers know to expect and plan for.
