Climbing "Selbstbetrug" (7+) in Arnstein Blöcke is a truly memorable experience. The route's name, meaning "Self-Deception," hints at the mental game involved. The crux lies in committing to insecure crimps and powerful moves, often tempting you to believe the hold isn't there or that the move is beyond your ability. The rock itself is classic Arnstein: rough and featured, demanding precise footwork and thoughtful hand placements. After the initial crux, a more sustained section of slightly less intense climbing leads to the anchor, leaving you with a feeling of both physical exhaustion and mental satisfaction. Successfully overcoming the 'self-deception' is the real reward on this route.
