This is the base of the Eiger North face in Switzerland. The ladders are necessary to reach the right spot to start with the climbing on the top of the Eiger.
The guys normally take the cog railway to the kleine Scheidegg and walk from there to the base. There they get ready with all the equipment to climb on the peak.
Me, myself did only the wonderful trail along the North face. I suffer with acrophobia, so, no chance for me to climb on a peak:-) I felt dizzy just watching them:-)
