In 2005 Blåmann suddenly gained international prominence after the Swiss, Didier Berthod and Giovanni Quirici, made a free ascent of Arctandria, rating the crux 5.13c. The two climbed the first five pitches on aid, fixed ropes and then spent six separate days working the route. Eventually, both climbers led every pitch. They used natural protection throughout and added no bolts. However, three of the pitches were only pinkpointed, and unsettled weather allowed no opportunity for a single-push ascent. Writing about the experience, Berthod praised the high quality of the climbing and was pleased to be able to climb the route without altering its character by adding bolts: the crux moves are only protected by two copperheads, making it a serious lead. With regard to a single-push ascent he noted, "the challenge is still there."

This challenge was taken up by Austrian's Hansjorg Auer and Markus Heid (Auer soloed the Fish on the south face of the Marmolada earlier this year). The pair made a one-day redpoint of Arctandria on July 15 and upgraded the crux to 5.13d (8b). With pitch grades of 12c (7b+), 13d (8b), 12d (7c), 13b (8a), 12b (7b), 13a (7c+), 12b (7b), 11d (6c+), 11a (6b), 11c (6c) and three easy pitches to the summit.

Arctandria is one of the hardest multi-pitch, traditionally protected climbs in Europe.
