The Brudertunnel fixed-rope route is a short, but worth-while route in the impressive Karwendel mountain range.
The Brudertunnel route at Pertisau, located at Lake Achensee, is the first Via Ferrata of Tyrol. Only a few years ago new hooks and securing elements have been mounted and now the via ferrata shines in new splendour. The name of this route derives from a natural channel called Brudertunnel or Lamstunnel, which is integrated into the rope route. This natural tunnel provides a great view and makes climbing a real pleasure! Generally this rope route is well secured and includes rather steep, nearly vertical rock faces.
Within a walk of 15 minutes, from the Lamsenjochhütte refuge (1,953 m) you reach the rock face, where the rope route starts with a rather plain ascent. A steep channel with a large number of hooks follows. Before you reach the natural tunnel you have to overcome some easy and more difficult passages. However, the first part of the tunnel is rather easy, at its end you have to climb an overhanging passage, which makes you reach the end of the route.
Following the ridge for about 15 minutes, you reach the summit, from where you can reach the valley in a 40 minutes' walk. Of course you can also combine the fixed rope route with the Lamsenspitze mountain (2,508 m). Caution: Slip hazard in the tunnel!
