With a HVV ticket you can use the bus line 111 for sightseeing. Since it’s a common bus, you get no explanations on what you see. Also it’s sometimes crowded and less enjoyable then. It may help to exit and wait for the next one. At any station you have 20 minutes before the next bus 111 comes.
You may start at Busbahnhof Altona: Pflugacker <–> Altona
