Climbing "Wirts Bros" (6+) on the "Untere Wand" is a truly rewarding experience. This route, located on the Lower Wall, offers a sustained and engaging climb with technical moves and satisfying holds. The rock quality is generally excellent, providing good friction and confidence-inspiring security. Expect a mix of crimps, pockets, and small edges, requiring precise footwork and efficient body positioning. While the grade indicates a 6+, the sustained nature of the route and the slightly exposed feeling can make it feel quite challenging. Thoroughly inspect each hold before committing to it, and be prepared for a pumpy sequence near the top. The views from the top, overlooking the valley, are a well-deserved reward for the effort. Overall, "Wirts Bros" is a classic route on the Untere Wand that is highly recommended for experienced climbers looking for a test piece at the grade.
