Do you know that: the aquatic warbler Acrocephalus paludicola is a tiny bird which breeds only in 40 places in the world, which are situated in 6 countries. Over 90% of its overall population occurs in only 3 countries: Belarus, Ukraine and Poland. The Polesie National Park is one of 12 most important breeding areas for the aquatic warbler globally and one of key areas for the breeding population in Poland and European Union.


The Bubnów Marsh is of the most precious peat bogs in Europe. Here aquatic warblers, Eurasian curlews, Montagu’s harriers and many more other wetland birds breed.

Trail description: The trail begins at the watch tower (GPS coordinates: 5122’33.30’’N; 2315’06.36’’E; elevation: 170 m) near the flood plain on the Bubnów Marsh in the Polesie National Park. From there we head north-eastwards along a dirt road, which runs through fields, a forest, meadows, towards Pikulawka-Kulczyn. As we reach forest for the second time, we see information boards of the Polesie National Park. At this point (GPS coordinates: 5122’38.54’’N; 2316’22.40’’E; elevation: 175 m) we turn right into a path leading southwards. On a great part of this path there is a wooden footbridge which facilitates movement through swampy areas. Having passed about 300 meters we reach the observation tower (GPS coordinates: 5122’28.16’’N; 2315’31.30’’E; elevation: 175 m). We come back to the observation tower by flood plain using the same trail.

The most important bird species to be seen or heard during the best season for birding: the aquatic warbler, the Montagu’s harrier, the hen harrier, the short-eared owl, the Eurasian curlew, the common snipe, the great egret, the crane, the Eurasian bittern, the spotted crake, the Eurasian penduline tit, the black-tailed godwit, the greylag goose, the ferruginous duck, the gadwall, the northern shoveler.

The “Aquatic warbler” Trail.

Other attractions in the vicinity of the trail: The village of Wereszczyn is worth visiting as it belongs to the group of the oldest villages in Polesie – according to historical sources Wereszczyn existed already in the thirteenth century. A must on the sightseeing list in this village is a baroque parish church under the invocation of St. Stanislaus from the seventeenth century with adjacent cemetery with historic gravestones. Moreover, in this village there is a manor-park complex from the nineteenth century and a monastery of the Community of the Brothers of Merciful Jesus. To the south of the village of Andrzejów there is a medieval gord from the thirteenth century. In Świerszczów we can visit a parish church under the invocation of St. Basil from 1875. Apart from that the “Aquatic warbler” Trail partly overlaps with the cycling trail “The Gord Trail”. From the tower on the flood plain on the Bubnów Marsh a Nordic walking trail “The Wereszczyński Trail” has also been marked out – the trail leads to Wereszczyn. In the village of Zastawie we can stop at small Lake Wereszczyńskie where a jetty, a shelter and parking lot have been located.
