Biebrza National Park
The fauna is diverse and dominated by water and mud birds with some extremely rare species. The park is Poland’s largest habitat of the elk. The park’s wildlife can be conveniently observed during guided rafting trips down the river course.
Built in the late 19th century, the fortress of Osowiec located in the Biebrza River valley is certainly worth a visit.
