Brunegghorn, Mountain summit in the Pennine Alps, Valais, Switzerland

The Brunegghorn is a 3,831 m summit in the Pennine Alps above Herbriggen on the west side of the Mattertal, about 3.5 km northeast of the Weisshorn. Its north face, up to 57° steep, dominates the lower Mattertal, while the broad, broken southeast side is the source area of the 1991 Randa rockfall. Ridges run northwest, northeast and southwest from the top.

The first recorded ascent occurred in 1853 when J. and F. Tantignoni reached the summit with Swiss guide H. Brantschen. Since then the peak has attracted mountaineers from different generations and regions.

The name Brunegghorn combines the Brunegg glacier and saddle with Horn, the German word for peak, reflecting the German-speaking side of the Mattertal above Herbriggen. The 1991 Randa rockfall started from the base of the mountain's southeast flank, and the event is still part of how locals describe the peak.

The normal route starts from the Bruneggjoch (3,365 m), reached in about three hours from either the Topali Hut or the Turtmann Hut. From the col, climbers ascend west of the rocky north-west ridge over firn to a saddle east of point 3,671, then follow the south-west ridge; a bergschrund can cause problems late in the season. The final 1.5 to 2 hours cross snow and scree to the summit.

The Abberg, Brunegg, and Bis Glaciers dominate the north face and show pronounced seracs and crevasses. These ice formations change noticeably from year to year and influence the route choices of experienced climbers.
