The Weisshorn is situated in the southern canton of Valais, about 25 km southwards from the Rhone between Sierre and Visp. It is the culminating point on the north-south orientated chain separating the Val d'Anniviers to the west and the Mattertal to the east and enclosing the Turtmanntal to the north, the tripoint between these valleys being located just north of its main summit. The Weisshorn faces the slightly higher Dom across the Mattertal, with the village of Randa 3100 metres below these two summits. After the Dom, the Weisshorn is the second-highest Alpine summit situated completely out the main chain and fully within Switzerland. On both sides of the Weisshorn range, the water end up in the Rhone, through the Navizence (west) and the Vispa (east). The Weisshorn and the Dom are only two of the many 4000-metre peaks surrounding the region of Zermatt, along with the Zinalrothorn, the Dent Blanche, the Dent d'Hérens, the Matterhorn and, second highest in the Alps, Monte Rosa.
