Belavezhskaya Pushcha (Białowieża Forest on the Polish side of the border) is the last remnant of the primeval forest that once covered most of the European Plain. It is a UNESCO World Heritage Site and the largest old-growth forest in Europe — trees up to 500 years old, standing in conditions that have barely changed since the last Ice Age. The forest is home to Europe's largest land mammal: the European bison, which was extinct in the wild by 1919 and restored through a captive breeding programme that started with animals from the very reserves that protect this forest.
A visit to the Belarusian side of the park typically includes the open-air museum area and the bison enclosures where you can see the animals at close range, as well as walking trails into the forest interior. Entry by car is restricted to protect the ecosystem; tours in horse-drawn carriages or on foot with a guide are the standard way to explore the deeper forest. The park is about 20 km south of Kamianiec.
