In a loop from Freybrücke (I took Bus M49 from Theodor-Heuß-Platz to Haltestelle Freybrücke) around Tiefwerder Wiesen.
A lovely walk – the wrong time of day to actually see any beavers – but we saw lots of traces of them, and one nutria, and then a lot of birds, including some I had never seen in real life before.
The photos are of variable quality but hopefully serve as “proof” :-).
