Climbing "Ohne Namen" on Hoher Stein is a memorable experience. While I don't have the exact grade information, Hoher Stein is known for its challenging routes, and "Ohne Namen" (meaning "Nameless" in German) likely presents a technical and demanding climb. The rock quality is typically excellent, offering good friction, but the climbing style often involves crimps, pockets, and precise footwork. The views from the top, however, are spectacular, making the effort worthwhile. Due to the route's name, finding detailed information online might be difficult without knowing the route's creator or a more specific description of its location on the wall. Be sure to check local guidebooks or consult with climbers familiar with Hoher Stein for accurate grade and route details before attempting it.
