Surf's up on the Eisbach River

It may be hundreds of miles away from any coastline, but the Bavarian capital of Munich is home to one of the world's most iconic - albeit dangerous - waves. The Eisbach wave, apparently appeared overnight in 1972, after the city submerged several concrete blocks under a bridge to block the river's strong current. This created an accidental constant flowing wave effect - one which experienced surfers immediately seized upon. Reporter Rebecca Rosman reports from Munich.
