He has done some incredible climbing in the Bernese Alps, especially on the Eiger. At the age of 20 he climbed the north face of the Eiger (3967m) in winter. In 1999 he was part of a large live broadcast of an Eiger North Face climb on Swiss television. The wall was climbed live in 30 hours with just two teams. Following on from this, in 2000 a new route was formed, La vida es silbar, on the same wall. In 2001, Siegrist forged the route The Young Spider together with Ueli Steck on the north face of the Eiger. In 2002, he climbed the north face of the Eiger with Michal Pitelka using historical equipment from the first ascents back in 1938. Again with Steck he climbed the north walls of Eiger, Mönch (4107m above sea level) and Jungfrau (4158m above sea level) in just 25 hours in 2004. In the same year he broke the record for rope teams in the north face of the Eiger with Steck. They completed the climb in nine hours, faster than Reinhold Messner and Peter Habeler 30 years earlier. Stephan Siegrist has climbed the north face of the Eiger over forty times.
Highlights include the following:
2006: "Golden Eagle", Aguilla Desmochada, Patagonia - first ascent together with Alexander Huber
2004: NW Ridge of Thalay Sagar (6904m)
2002: Dos Cumbres North-Pillar first ascent in middle of the Patagonian icefield
2001: "The Young Spider" (7a/A2, WI 6, M7), Eiger North Face first ascent together with Ueli Steck.
2000: "La vida es silbar" longest – hardest alpine sports climb on the Eiger North Face
1999: Siegrist made the historical first winter ascent of Cerro Torre, Patagonia together with David and Thomas Ulrich and Gregory Crouch.
In addition to these highlights, he has taken part in different climbing projects. Not only does he know his way around bouldering and sport climbing, he is also familiar with big wall, ice and mixed climbing.
In June 2016, Stephan Siegrist set an exceptional world record on Kilimanjaro at 5700m above sea level. He crossed a 20m long highline stretched between two rock towers.
Stephan Siegrist feels very lucky to have found not only his profession but also his calling in mountaineering.
“I always had the opportunity to be able to do sports with disadvantaged children. For me it was always a nice and enriching experience to see how much joy the children had and how grateful they were. Together with Laureus, we want to make sporting activities possible for many more children.”
