Carabiners rattle, hooks clink, ice splinters trickle. With one hand you hit an ice axe into the wall and ram the crampon into the ice. A little break. Take a deep breath and carry on. Step by step you climb the cascades of the frozen waterfall, which shimmers in the light in different shades of blue. The last piece of freedom. That's how an ice climbing adventure in the Sertig valley could feel like. Even if you want to put crampons under your shoes right now: Prepare yourself well first - and take your first steps in the ice together with a mountain guide.
