Liwia Łuża, Coastal lake near Niechorze, Poland.

Liwia Łuża is a shallow coastal lake near Niechorze in northern Poland, connected to the Baltic Sea by a channel. Its shores are lined with dense reed beds, and the surrounding area is a mix of forest, dunes, and wetland.

Until 1945 the lake was called Horst-Eiersberger See, after the villages of Horst (now Niechorze) and Eiersberg (now Skalno) on its shores. The Polish name Liwia Łuża was officially established in 1948. The nearby village of Skalno still carries the memory of Eiersberg in its German name.

Liwia Łuża is an ornithological reserve where wild swans and water birds nest in the reed beds along the shore. Walking the trail that circles the lake gives a close view of these birds during their breeding season.

A green-marked trail circles the lake and links three nearby towns, with several entry points along the route so visitors can join or leave the path at different spots. The terrain is mostly flat, which makes the walk manageable for most people.

The channel linking the lake to the Baltic is about 1,000 metres long and also bears the name Liwia Łuża. Between the bridge on Wojska Polskiego Street and the river mouth, gates act as a one-way valve: they let the lake drain into the sea but block storm surges from pushing seawater back in, limiting the backflow that can reach the Lądkowski Canal.
