Really fun dyno on a mostly blank wall!
Under "Reichsbrücke" on the Donauinsel side, go upstream about 400m, not directly at the Donau, a bit above the bright blue wall.
Start with your feet high on the metall thing sticking out from the wall and the wooden doorframe for your hand. Reach the 2 lines, use the small circles for feet and dyno to the top :)
FB 6B ish, if you are 180cm or so...
