Climbing 'Sonne um 11' (German grading system 5+) in 'Düsterer Winkel' is a rewarding experience for climbers comfortable with moderate slab and slightly overhanging terrain. The route name, 'Sun at 11', might be ironic given the 'Düsterer Winkel' or 'Dark Corner' location, suggesting it's more about the challenge than basking in sunlight. Expect good friction on the rock, and a few thoughtful moves to overcome the crux. While generally well-protected, a cool head and solid footwork are essential. The descent is typically a walk-off or rappel depending on the setup. It's a classic route that provides a solid introduction to climbing in this specific crag.
