Since 1992 Huber has been a state-certified mountain and skiing guide. He is most famous for climbing big walls in the
Himalaya. In 1997, Huber, his brother Alexander, Toni Gutsch, and
Conrad Anker went to climb Pakistan's Latok II, in his first trip to the
Karakoram. At the time, Huber felt he was still inexperienced, but credits his strong team and good weather for the successful ascent, which encouraged him to become a professional mountaineer. The 2007 documentary
To the Limit shows him and his brother
speed climbing. In 2014, Huber and his brother committed to climbing Latok I's north face in Pakistan, one of the last unclimbed problems in the Himalayas. He would commit the next decade to climbing Latok over the course of several expeditions. The next year he returned for another unsuccessful attempt, where he and his brother were nearly scraped from the mountain by an avalanche. Huber described the experience as follows: “It is clear to me that the north face of Latok I is so incalculably dangerous that I feel no more motivation to tackle it. I’m looking for other difficult goals without this incalculable risk.” In July 2016, Huber had a sixteen-meter free fall while being filmed at a wall on the
Brendlberg in the vicinity of
Berchtesgaden and suffered a skull fracture. By August 2016 he had recovered enough to go on the next expedition, once again to Latok I. The attempt was unsuccessful. In 2019, he once again attempted the north face of
Latok I, but was unsuccessful, but returned for another attempt in 2024. In late July 2025 Huber took part in the rescue attempts for German climber and former biathlete
Laura Dahlmeier, who went missing after being hit by a
rockfall while climbing
Laila Peak in northern Pakistan. ==Personal life==
