The exposure is moderate, adding to the feeling of adventure. The crux often lies in maintaining balance on the polished sections and finding the optimal sequence of moves. Successfully topping out "Katastrophal" provides a satisfying sense of accomplishment, especially considering the name! It's a great route for honing your technique and practicing efficient movement on varied terrain. Don't underestimate it, and be prepared for some thought-provoking climbing.
