At 4,478 m, the Matterhorn is the most difficult classic in the Alps. The climb and descent is done exclusively over rocks and ice, and it requires outstanding fitness and experience in rock climbing with and without crampons. The normal route is via the Hörnligrat and is only suitable for well-versed mountaineers accompanied by a mountain guide.

This trail leads to what is probably the key location in Zermatt, the Hörnli Hut at the foot of the Matterhorn. Historically this has been the heart of all the action, and remains so today.

The Rothorn Hut attracts a colourful variety of mountaineers seeking high-altitude challenges. Regular mountain hikers, too, enjoy the climb up to the Eseltschuggen.
