The "twins tower" rises directly to the south of the main summit of Salbit, and starts slightly to the west. Home to numerous, long routes on bomber granite, this tower has a distinctly alpine feel, and has a snowpack at the base of most climbs even in late August. Recommended to bring an ice axe to cut steps, or crampons, to safely cross the snow field. Or do like we did and find two rocks shaped like daggers, then use them as handholds while you kick steps across....
From the Salbit-hutte, follow the trail west towards Salbit. The Zwillingsturm wall rises above the Biwak, and you'll know you're there by the snowpack at the base and your position west of the main summit.
