The park protects the largest complex of peat bogs in Poland, some of which are over 10,000 years old.
It is a crucial refuge for the rare aquatic warbler, with the park supporting a significant portion of the global population.
The Biebrza river valley is a 'dying' river system, meaning it maintains its natural, meandering course without significant human regulation.
Eurasian elk in the park are known to traverse flooded meadows by swimming through deep channels.
The park contains the 'Red Bog' (Czerwone Bagno) reserve, one of the oldest nature protection areas in Poland.
The water level in the valley can rise by several meters during spring, temporarily transforming the meadows into a vast lake.
It is one of the few places in Europe where wolves, lynx, and otters coexist in a largely undisturbed wetland habitat.
Biebrzański Park Narodowy is Poland's largest national park, encompassing the extensive Biebrza River valley and its unique peat bog ecosystems. It protects one of Central Europe's most significant refuges for wetland-dependent bird species. The landscape is dominated by dynamic marshlands, peatlands, and riparian forests that undergo seasonal flooding. It serves as a primary habitat for the Eurasian elk, the largest population of which in Poland resides within the park's borders. The park is characterized by a lack of large human settlements, preserving a vast, untamed wilderness. Visitors navigate the park primarily via elevated wooden boardwalks designed to protect fragile bog vegetation.
The elevated observation tower near the Długa Luka boardwalk offers a panoramic view of the vast, open marshland.
Wear high-quality, waterproof hiking boots to handle unpredictable boggy terrain outside of boardwalks.
Carry high-strength insect repellent, as the marshland environment hosts dense populations of mosquitoes and biting flies.
Bring binoculars for wildlife viewing, as animals are often spotted at significant distances across the open wetlands.
Attempting to explore off-trail during the spring flood season, which poses severe risks of getting stuck in deep mud.
Entry requires a valid park permit, which can be purchased digitally; certain trails may be periodically closed due to high water levels or nesting periods.
Stay strictly on marked paths to prevent soil erosion and disturbance to nesting wildlife; dogs are not permitted in most core protected zones.
