Äußerste Bum (rated 8-) in the "Other Routes" sector is a powerful and engaging climb. It’s a route that demands precise footwork and a good understanding of body positioning. The crux likely involves a series of crimps and a tricky transition onto a slightly overhanging section. The name suggests a demanding and perhaps somewhat exposed position. The rock is likely to be solid with good friction, but be prepared for potentially sharp holds. A few well-placed cams or nuts might offer peace of mind, though it's likely mostly bolted. The overall experience is one of commitment and satisfaction upon reaching the top, having overcome a physically and mentally demanding challenge.
