Katzensee Nature Reserve is a serene natural area featuring two small lakes surrounded by wetlands and woodlands, offering accessible outdoor recreation and wildlife observation just outside Zurich’s urban landscape.
Katzensee Nature Reserve encompasses approximately 66 hectares around two small lakes, Grosser Katzensee and Kleiner Katzensee, located on the northwestern edge of Zürich, Switzerland. This protected area is characterized by its diverse wetlands, reed beds, meadows, and mixed woodlands providing critical habitat for a variety of bird species and aquatic life. The reserve’s flat terrain and well-maintained paths make it an accessible destination for walkers, birders, and families seeking a peaceful nature escape close to the city. Historically, the Katzensee area was utilized for peat extraction and small-scale fishing before gaining protected status to preserve its delicate ecosystems. Today, it is managed to maintain biodiversity, with efforts focused on wetland conservation and invasive species control. Visitors often enjoy birdwatching, picnicking, and seasonal swimming at designated lake spots. The reserve’s boardwalks provide intimate views of the flora and fauna, and several interpretive signs highlight its ecological significance. The reserve is also an important green lung for Zurich's neighboring communities, offering tranquil natural beauty amid urban development. Whether for educational outings or gentle hikes, Katzensee Nature Reserve delivers a refreshing outdoor experience paired with outstanding opportunities to observe native Swiss wildlife in a relatively compact, well-maintained natural setting.
