Trzcielińskie Swamp is a strict protection area, a part of the Wielkopolski National Park. It spreads over 38,14 hectares, including a largely overgown and swampy Lake Trzcielińskie in the valley of the Samica river. This area is a nesting site for over 60 species of birds, so you might want to bring a pair of binoculars! Start your observation from the birdwatching tower. Some of the bird species observed here include peewit, grey heron, marsh harrier, common buzzard, red kite, and also crane and oriole.
