The forest reserve was established by the ordinance of the Minister of Environmental Protection, Natural Resources and Forestry of December 31, 1993, on an area of 160.56 ha. It was created thanks to the efforts of prof. Witold Rosa, head of the Forest Management Department at SGGW in the years 1977-1985. It is located on the south-eastern edge of the Nieporęt commune, in the fork of the Marki-Nieporęt and Marki-Legionowo roads, on the Czarna river. The name refers to the historical forest in the vicinity of Słupno, which was heavily thinned by logging and peat exploitation. The reserve is dominated by riparian forest, alder swamps, oak-hornbeam forests, and mixed coniferous forests. 80% of the tree stand is alder and birch. Rez. “Puszcza Słupecka” is one of the most valuable forest areas in Mazovia. Many rare protected plant species occur here, including the mezereon (Daphne mezereum) – a highly poisonous plant whose fruits can cause human death if ingested. In the reserve, golden orioles, black storks, and cranes nest, and moose, roe deer, wild boars, raccoon dogs, and foxes occur, as well as the adder among reptiles.

The "Barbarka" stronghold is the remains of one of the most important strongholds in Mazovia. Located in a strategically important location on the route from Mazovia to Ruthenia, it guarded a river crossing. Serock also had a customs house. The early medieval stronghold and its surrounding settlements gave rise to the later city. Source: https://zabytek.pl/pl/obiekty/serock-grodzisko-barbarka

The path is approximately 3.5 kilometers long (one way) and leads from Dziekanów Leśny to the monumental oaks in the recreation clearing. The path has a forest character, initially running through a pine forest, and then through the Sieraków reserve - one of the most valuable areas of strict protection in Kampinos. The route is from Dziekanów Leśny - Zboiński's stone - Plapis' stone - a clearing near Stary Dęb in Posada Sieraków. You can return the same way to the parking lot in Dziekanów (or the bus stop), or make a loop, first following the green trail, and then the red trail, going around Bagno Sieraków.
