Climbing 'Runenstein' (grade 6) in Trutzburg is a memorable experience. The climb itself is characterized by its technical nature, demanding precise footwork and body positioning. The rock is generally solid, providing good friction, but expect small crimps and subtle features. A key section involves a delicate traverse to overcome a small overhang, requiring commitment and careful weight distribution. While not overly strenuous, 'Runenstein' requires sustained concentration and a good understanding of climbing technique. The reward is a satisfying ascent of a beautiful line in a truly impressive setting.
