A lake slowly overgrowing and turning into a swamp. Unfortunately, it has its own dark history https://trojmiasto.eska.pl/policja-znalazla-cialo-w-zbiorniku-lepusz-znaleziono-grzegorza-borysa-aa-8xy4-xZp5-WT7A.html

The only option to cross Lake Kackie (apart from going around it). On the eastern side, the beginning of the causeway is near the only concrete pillar. On the western side, you have to walk along the PKM embankment on the only trodden path. The causeway is worth visiting in late summer/early autumn, when birds gather on the lake to fly away. After heavy rains, its top can be flooded.
