With nothing planned for Sunday, we randomly took a stroll along the harbour and we reached Landungsbrucken whereby there is a regular ferry service that takes you to stops along the bank. The great thing is that the service is included in your daily travel card.

We also found a sandy beach front next to the river bank at the Neumuhlen dock.
You can get more information by going to the official Hamburg transport website along with the ticket prices.
