Rimpfischhorn, Alpine summit in Pennine Alps, Switzerland

Rimpfischhorn is a summit in the Valais Alps that reaches 4,199 meters and connects the Monte Rosa group to the Mischabel peaks. Its western and northern slopes are covered in ice, while the eastern face presents steep rock bands.

Leslie Stephen and Robert Liveing completed the first recorded ascent in 1859, guided by Melchior Anderegg and Johann Zumtaugwald. This climb marked an early milestone in modern Swiss mountaineering during the golden age of Alpine exploration.

The name Rimpfischhorn refers to the mountain's ridged, wrinkled rock face, and the peak marks the highest point of the municipality of Saas-Almagell. Its summit stands on the border of Täsch, Zermatt and Saas-Almagell, and the nearby Allalinhorn lies less than 3 km to the north.

Climbers typically begin from the Britannia Hut at 3,030 meters, where ice axes and crampons are essential equipment. The glacial route demands mountaineering experience and proper acclimatization.

The north ridge ends at the Grosser Gendarm, a sub-peak of 4,107 m. The summit itself lies on the border of three municipalities: Täsch, Zermatt and Saas-Almagell, and is the highest point of Saas-Almagell. In 1971 Albert Siebenmorgen reached the top at the age of 77.
