This mountain is somewhat similar to мount Rundle. Maybe the geometry in the image. Platform for acceleration from the bottom up to then jump.

What is the most difficult hike you have done?

I like walking in the mountains, but not the rocky mountains. I was once in the High Tatras. The impressions remained until now. Especially the view of the clouds from above. So. The view...wow, but the uphill climb was extreme. I'm not an extremist ;-)
Therefore, sometimes I go to the Carpathian mountains near me. They are lower and not so rocky.
