The Port of Hamburg, the Hamburger Hafen, encompassing 100 square kilometers of tidal harbor, is known as the Gateway to Germany.
It's also where you'll find many of the city's important attractions - and on summer evenings and weekends plenty of local residents relaxing.
A lovely pedestrian trail takes in the old 19th-century Warehouse District, with its continuous lines of tall brick buildings once used to store tobacco, coffee, dried fruit, and spices.
Another landmark is the Köhlbrandbrücke, a 3.9-kilometer bridge that spans the harbor.
