I went to that wave in Munich a couple years ago. It is pretty rad to watch. I guess an Aussie living there found out how to make it. If you look under the bridge you can see a cable on each end that is connected to a huge board that forms the wave.
The best part... It is right next to the largest outdoor beer garden in the world.
Actually I was there whole last weekend and enjoyed lot of beer and precel
I didnt have time to try it. Also water was pretty chilli - aprox. 8°C. No wonder that creek is called Eisbach = Ice creek
I plan to come back with my board during summer.
