Climbing 'Oarschwarzsammlung' (grade 8+/9-) in the Wachau / Waldviertel is a truly memorable test piece. This highly demanding route, named with such evocative quirkiness, is a fantastic challenge on the region's characteristic granite/gneiss. Each move requires a blend of power and intricate technique, pushing your limits on steep sections and delicate crimps. It's a route that demands full commitment, but the satisfaction of reaching the top, with the beautiful Wachau scenery stretching below, is immense and makes every struggle worthwhile.
