Nature reserve Świder, Nature reserve along Swider River, Mazovia, Poland
The reserve spans 41 kilometers of the Swider River and 5 kilometers of the Mienia River, featuring numerous meanders, cascades, and natural riverside vegetation.
The Polish Ministry of Forestry and Timber Industry established this protected area in January 1978 to preserve the natural river ecosystem and its surrounding environment.
The reserve includes multiple observation points where visitors can watch 120 bird species, including kingfishers, sand martins, and various woodpecker species in their natural habitat.
A blue hiking trail runs along both riverbanks, connecting the village of Glinianka to the town of Otwock, providing access to the most interesting sections.
The reserve contains 25 fish species, representing 22 percent of all known fish species in Poland, along with otters and northern water voles.
