The park stretches over the areas of Central Roztocze and the Biłgoraj Plain. The lay of the land is fairly flat with characteristic plains, small hillocks (up to 320m ASML), dunes, peat-bogs and swamps. Forests account for 85% of the area. River knickpoints forming scenic small waterfalls – a geological curiosity of the park – are particularly impressive on the Tanew River and the Sopot River. These ‘murmuring cascades’ can be seen in the ‘Czartowe pole’ and ‘Upon the Tanew’ nature reserves. Crystal-clear streams of the park are home to the grayling and the brown trout. There is also a growing population of wolves and lynxes.
