In the winter, you might get lucky enough to visit when the river is completely frozen and it is safe to skate! I am planning on taking part of this tradition in the coming few years.
Love sailing here and going on a river cruise would be a great idea to get to know the city's riverside attractions and the beauty it has to offer.
I was lucky enough to be visiting Hamburg in 2012 where there was this huge lady sculpture in the river placed there for only 10 days! The area was so crowded in order to see the funky art!
