Climbing 'Happel' (10-/10) in the Vienna Woods is a true test of physical and mental strength. The route, characterized by its technical crimps, powerful reaches, and subtle footwork, demands precision and unwavering focus. The initial section involves delicate traversing on small holds, leading to a crux sequence of dynamic movements between sloping pockets. Finding the right body position and maintaining tension is key to unlocking the sequence. The upper section provides a slight reprieve, but still requires sustained effort and careful route-reading. Reaching the top feels like a hard-earned victory, rewarding the climber with stunning views of the surrounding forest.
