Białowieża Forest

The last remaining part of the primeval lowland forest that once covered Europe, shared with Belarus, a UNESCO World Heritage Site. It's home to Europe's largest population of wild European bison, the continent's heaviest land animal.

The strictly protected zone can only be visited with a licensed guide. The European Bison Show Reserve lets you see bison, as well as tarpan horses and elk. Walk the Royal Oaks Way among ancient trees, or cycle the forest roads. It's about 4 hours from Warsaw.
