A wetland of birds beside the city

The reserve's whole reason for existing is its birds. Around 100 species breed here and roughly 50 more turn up on migration, for a running tally of about 130. Among the nesting waterbirds are four different grebes—great crested, red-necked, black-necked and the little grebe—along with mallard, greylag goose and mute swan drifting across the open water.↗↗

Two colonies are the highlights. On the tree-covered island in Falencki Pond a heronry of grey herons nests alongside great cormorants, while the reedy margins of Puchalski Pond hold a large colony of black-headed gulls almost at the roadside. Keep a wider eye out too: osprey, white-tailed eagle and western marsh harrier hunt over the ponds, and the reed beds shelter the booming great bittern, kingfisher, Penduline tit and reed warblers.↗↗↗

In spring and autumn the drained, muddy shallows of the ponds become a refuelling stop for waders—snipe, redshank and green sandpiper pick their way along the exposed bottoms while the fish farms work their seasonal cycle.

Old fish ponds, deliberate landscape

These are not wild lakes but a managed complex of breeding ponds—commonly described as eleven carp ponds (the water surface across the whole system runs to some 94 hectares), strung together by grassy embankments and small tree-covered islets. Some basins were cut into marshy ground as early as 1784, and large-scale fish farming began in 1839 under the Warsaw merchant Jan Spiski, who still gives his name to one of the southern ponds.↗↗↗

That centuries-old pattern of shallow water, reed fringes, sedge islets and willow-and-poplar thickets is exactly what makes the place so alive: it forms a mosaic of habitats that, on this heavily developed stretch of the Masovian plain right by Warsaw, has no real equivalent for water and marsh birds.↗

Walking and watching the ponds

You explore the reserve on foot along a single signed circular trail that runs the embankments between the ponds. It is flat and easy, and three observation towers and platforms look out over Falencki, Raszyński and Parkowy Górny ponds, giving elevated views across the water and the surrounding meadows.↗↗

The path doubles as an educational trail with seven themed stops—covering the reserve's residents (slow worm, dragonflies, greylag goose, common carp), its water and marsh birds, migration, food chains and conservation threats. Posts carry QR codes linking to the free "Mazowieckie rezerwaty przyrody" (Mazovian Nature Reserves) app, which maps the route and adds games and quizzes, making it welcoming for families and school groups.↗↗

A broad-leaved ash avenue running along Aleja Hrabska is itself a protected nature monument, its trees some 150 years old, and it frames the walk toward the old estate.↗

Layers of history in the reeds

The ponds and their embankments carry real historical weight. The Falencki causeway (Grobla Falencka) was a bloody point in the battle of Raszyn on 19 April 1809, when Polish forces under Poniatowski faced the Austrians and Saxons; a stone raised by the PTTK marks the battle's 150th anniversary. A martyrdom monument here recalls Pawiak prisoners and local villagers shot by the German occupiers in 1943, and a late-Baroque sandstone figure of God the Father dates from the end of the 18th century.↗↗

At the reserve's edge sits the Falenty palace-and-park complex, an early-Baroque seat begun around 1620 and today the home of the research institute that manages the grounds—the fibre artist Magdalena Abakanowicz was born on the estate in 1930. The palace and park are a natural add-on to a visit, reached at the end of the ash avenue.↗↗↗

Getting there and good birding

The reserve lies between Raszyn and Janki, straddling both sides of Aleja Krakowska (the national road heading south to Kraków and Katowice), roughly 15 km from central Warsaw. You can arrive by Warsaw suburban buses (lines such as 703, 706, 707, 721 and 728, alighting at the IMUZ or Puchały stops), and there are parking options near the ponds and the Falenty institute.↗↗

Birding is good all year, but spring is the classic season—full colonies, singing reed warblers and the bittern's booming make the most of a short trip. Early mornings and late afternoons are best for activity and light, and the open landscape means you rarely need a telescope, though binoculars are essential for the distant colonies.↗↗
