Climbing "Quertacker" (6-) in Arnstein Blöcke is a rewarding experience for climbers seeking a well-protected and enjoyable route. The route follows a prominent horizontal traverse (hence the name, likely referencing a stapler or something similar) across a block, demanding good footwork and precise hand placements. The holds are generally positive, but the horizontal nature requires sustained effort and good body positioning to avoid tiring quickly. While not overly strenuous, the continuous nature of the traverse and the need for accurate movement make it a solid test of technique at the 6- grade. The rock quality in Arnstein Blöcke is generally excellent, providing good friction. "Quertacker" is a popular route, so be prepared to potentially wait in line, especially on weekends. Overall, it's a recommended climb for those looking to hone their traversing skills in a beautiful and well-maintained bouldering area.
