The striking Zervreilahorn perched way back in the Valser Valley is a sight to behold. The Northeast Ridge is athletic climbing on alpine rock. Despite the retrofitting, it is still a serious climb and retreat is difficult. The rappel route is equipped for 1 x 50m ropes. You can also rappel down the route “Nanouk” with 2 x 50m ropes. The routes on the steep South Face are unbelievably beautiful. Despite the excellent protection on “Medea”, this is probably a route more appropriate for the “Swiss Extreme” series.
