At this altitude you can decide to continue hiking along the ridge (T3) - very challenging - or to take the turnoff to the right (T1).

Small cave (dug out) with a table and fireplace. Access from the north via ladders.

The route from the bottom is incorrectly navigated; ignore the left turn sign. There's simply a point where there's no way back and the climb is extremely dangerous. There's no solid ground and hardly any way to hold on. We almost called the REGA (Rega Rescue Service).
