HVV – Hamburger Verkehrsverbund -public transport company of Hamburg. Beside metro and subway trains as well as busses here we have the public ferries. Every 15 minutes the ferry number 62 travels from Landungsbrücken to Finkenwerder and back (just stay on the ferry). If you have a common HVV-ticket for the day or single ticket for € 2.85, don’t miss it.
Fortunately there are no annoying voices from bad speakers trying to explain the harbour with unfunny jokes. Step up on the roof, enjoy the wind and the great view. Start at Landungsbrücken Bridge 3, ferry 62, short stops at Altona/Fischmarkt (see the Fishmarkt article), Dockland/Fischereihafen (see the Dockland article), Neumühlen/Övelgönne (Elbstrand), Bubendey-Ufer and Finkenwerder and back.
If it is too cold, walk down inside the ferry, with great view, too. They even serve hot and cold beverages!
