Rüdiger Steuer, who made a lot of first ascents, write on his website: "Standing close to the national park border, there is no ascent ban, but there are rumors about it. In this regard, climbers have already been approached by rangers. However, there is neither an official publication by the authorities nor any other accessible reason for a ban. So no climber cares. However, a queasy feeling of possibly doing something forbidden remains. This applies to possible first ascents that can be seen from the street. Possibly addressed by rangers, one should always not understand the language, play the innocent, but without arguing. "
