The river Isar is swollen and provides some city river surfing as the water flows under the Reichenbach Bridge. You can see part of the wall behind them. The river is probably 5 or 6 times wider than their normal practice ground on the Eisbach. Nevertheless it is dangerous and forbidden by the local bylaws.
The surfers and a couple of canoeists were queuing up to take advantage of the surf. There were dozens of spectators on the bridge above and on the banks of the river. Normally surfers took to the waves one at a time, but these guys were out at the same time. This particular manoeuvre looked pretty daring to me.
