The South Ridge is the classic and best-known mountaineering route on Riffelhorn. It is generally considered an easy alpine climb with short sections of rock and mixed terrain. The route is popular as a training and acclimatization objective above Zermatt. Despite its modest difficulty, the ridge can feel exposed and requires secure movement on alpine rock. Conditions and route-finding can vary, especially if snow or ice remains on the upper sections. It is commonly climbed as a day outing from the Zermatt area.
