Translation of ineffectiveness in German

I don't remember exactly what we did there, all I remember was that there was some show including a snake and a Janasene tourist agreed to have the snake on her neck. I almost fainted just by watching.
We joined the mass and climbed it. The stones were a little slippery and I doubt that this place is accident free. Climbing big slippery stones was not an easy task but we managed it slowly.
The view of the valley, the lakes and the surrounding volcano mountains were breathtaking. We stayed there for nearly one hour and had a little snack. From there we continued to have lunch.
