The Lamsenspitze fixed-rope route through the Brudertunnel channel is a day tour in the beautiful Karwendel mountain chain.
The Brudertunnel - or Lamsenspitze - fixed-rope route (Brudertunnel Klettersteig) near Pertisau at Lake Achensee is the first via ferrata of Tyrol: In 2002, it was completely renovated. Its name derives from a natural channel on the upper part of the route, called Brudertunnel or Lamstunnel. The natural opening was enlarged and made accessible after WWII by the brothers Franz-Karl and Toni Unterlechner. From the Gramai Mountain Hut you reach the starting point of the fixed-rope route, the Lamsenjoch Mountain Hut (1,953 m a.s.l.), in a 2-hour hike on well marked paths.
The Brudertunnel fixed-rope route is well secured and includes nearly vertical rock faces. From the Lamsenjoch Mountain Hut, the route leads through the steep walls of Mt. Lamsturm and Mt. Steinkarlspitze (2,460 m a.s.l.). Before you reach the natural tunnel, you have to overcome some easy and more difficult passages: However, the first part of the channel is rather easy, at its end you have to climb an overhanging passage. After 15 minutes there's the Lamsscharte ridge, from where you reach the Lamsenjoch Mountain Hut by descending on a wide rubble cirque. You can also combine the fixed-rope route with an ascent to the peak of Mt. Lamsenspitze (2,508 m a.s.l.).
