Tête à Pierre Grept, Mountain summit in Bernese Alps, Switzerland

Tête à Pierre Grept is a summit of the Bernese Alps on the border between the cantons of Vaud and Valais, reaching 2,903 metres. It rises between the Grand Muveran and the Pas de Cheville, and its northern side holds the small Glacier de Paneirosse.

The summit sits on the natural border between Vaud and Valais cantons in Switzerland. This geographic marker has served as a territorial boundary for local communities.

The name refers to a man named Pierre Grept, according to historian Jean-Paul Verdan. One account links it to a criminal tried in December 1749 and sentenced to beheading by sword, whom locals may have commemorated ironically, perhaps under the influence of the legend of the Quille du Diable and the June 1749 landslide. Another account names a chamois hunter who lived in the region.

The summit lies between the Grand Muveran and the Pas de Cheville, on the Vaud–Valais border; the Glacier de Paneirosse occupies the northern side. Approach routes are not marked in the sources, so plan the ascent from the Muveran or Cheville side with a map and check snow and ice conditions on the north face before setting out.

The northern face borders Glacier Paneirosse, where seasonal ice changes alter the appearance and climbing conditions significantly. Visitors may notice the stark contrast between bare rock and frozen slopes.
