Fürenwand is a very demanding via ferrata with difficulty D-E. It lasts about 3 hours with an altitude difference of 765 meters. It is very popular, and a bit crowded.
Usually, the Fürenwand via ferrata is open from the end of May until mid-October depending on ice conditions and temperature. In 2016 it was opened late at mid-June.
Usually, the best months for Fürenwand are August to October. You have to pass a water wall after two-thirds of the via ferrata. At this time of the year, you may not get wet except in 2016 and after heavy rainfall the day before. It is advisable to start early, before midday. Even with less than 20 degrees, it gets hot while climbing. After 12 p.m. the Fürenwand (wall) is completely in sun.
