Nature reserve Jeziorko Czerniakowskie

Nature reserve Jeziorko Czerniakowskie is Warsaw's largest natural water body, a lake that stretches several kilometers across roughly 47 hectares within the city limits. Dense vegetation, shallow shorelines, and wooded areas frame the water and define the space.

The site gained protected status through a ministerial decree in 1987, decades after the city acquired it in 1938. This extended history of ownership and safeguarding reflects Warsaw's effort to preserve this natural landscape.

The reserve draws people seeking outdoor time near the city, where walking trails and waterside paths invite regular visits for bird-watching and quiet moments in nature. Families and nature enthusiasts routinely use the space as an escape from urban surroundings.

Access is through Jeziorna Street, where visitors find a beach and swimming area meeting European Union bathing standards. Walking paths and shoreline areas are most accessible during dry months when trails remain passable.

The reserve holds around 60 bird species and rare aquatic plants such as the yellow water-lily thriving in the clean water. Beavers inhabit the area and aid natural water retention through their activities.
