Going westwards along the river Elbe is one of the most scenic walks in Hamburg. This is especially true during sunset since you are walking towards the sunset. I quite like the area at Altonaer Hafen since it is definitely less crowded than the Alster lake walk or the inner city region. You pass the famous Dockland office building which is shaped like a parallelogram. Opposite of the building they left an old harbour crane giving a nice contrast towards the modern glass and steel buildings. Finally you reach the tug boats harbour where all the boats towing the big container vessels wait for their next call. The light that evening made for a nice similar sunset and golden hour look.
