The Kampinos National Park is situated in east-central Poland, in the Masovian Voivodeship, on the north-western outskirts of Warsaw. It covers the ancient Kampinos Forest. In January 2000 the area was added to UNESCO’s list of biosphere reserves. On the map walking, cycling, skiing and horse trails are marked, e.g. Kampinos Cycling Trail whose total length is around 200 km.
