Beat Kammerlander began climbing at the age of 18 and was in a short time part in the newly established sports climbing scene. He was soon one of the world’s best sports climbers and developed significantly the sportclimbing in Austria. Already in 1980 he climb in winter the of the Eiger north face and a year later a solo ascent of the „Mittelpfeiler“ on Heiligkreuzkofel (VIII-). The legendary Messner route.

Beat was known for his first ascents in the alpine walls. It’s began with his first ascent „Unendliche Geschichte“ in 1991 in Rätikon. It the first alpine route in the upper tenth grade (UIAA).

His route „Silbergeier“ (X+) from 1994 was one of the three hardest alpine tours in the world and is, with „End of Silence“ by Thomas Huber and the route „Des Kaisers neue Kleider“ by Stefan Glowacz, part of the „Alpentrilogie „. All three routes are in the upper tenth UIAA grade and was on the upper point of the climbing difficulties for multi-pitch routes much higher. Beats Route „Silbergeier“ has established over time as the most popular route of this trilogy.

In 1997 he bolted the seven pitch long route „WoGü“, once again in the Rätikon and made it the first ascent. Adam Ondra did the first redpoint ascent until 2008.

He has also been very successful in „short“ routes, with „Speed“ (XI- / XI) and „Missing Link“ (XI) on Voralpsee in Switzerland, two extremely difficult routes. In 2009 he was able to write climbing history with the clean ascent of his route „Prinzip Hoffnung“ at the Bürser Platte in Vorarlberg. Beat Kammerlander graded the route with X/X + or E9-E10. The E-grade is still an estimation of overall difficulty experienced by a climber leading a route on-sight. In 2017, after more than four years of trying in Rätikon, he managed in one of his difficultiest first ascents „Kampfzone“ (8a obligatory, 8c). The route represents the last highlight in his climbing career.
