Fletschhorn, Alpine summit in Valais, Switzerland

Fletschhorn is an Alpine summit located in the Walliser Alps, positioned between the Saas Valley and the Simplon Valley in southern Switzerland. The mountain rises prominently in this region where two major valleys converge below its slopes.

The first ascent was made on 28 August 1854 by the priest Michael Amherdt of Simplon with guides Johannes Zumkemmi and Friedrich Clausen, via the Rossbodengletscher and the north-east ridge, when the peak was usually called Rossbodenhorn. The north face was first climbed on 25 July 1928 by Émile-Robert Blanchet with Oskar Supersaxo and Kaspar Mooser, who needed 5½ hours for the wall and 6 more for the approach from Simplon.

The name Fletschhorn was long applied to the whole northern part of today's Weissmies group, which was called the Fletschhorngruppe; the Lagginhorn was known as Süd-Fletschhorn and today's Fletschhorn as Rossbodenhorn. In February 1988 the municipality of Saas Grund filed a building application with the Valais building commission to restore the mountain's original height.

Mountaineers use the Fletschhorn-Biwak shelter as a base for climbing attempts. Visitors need mountaineering experience and comfort with heights, so arriving fully equipped and well-prepared is essential for any attempt on this peak.

The north face of Fletschhorn remained unconquered until July 1927, when E. R. Blanchet and guides Oskar Supersaxo and Kaspar Mooser achieved the first ascent.
