 The park is covered in dry sclerophyll (hard leafed) forest - mostly eucalypt and has fairly frequent forest fires.It is largely an untouched wilderness area and receives very few visitors, as it has virtually no facilities and is fairly remote, despite its proximity to Sydney.The Nattai National Park is one of the eight protected areas that, in 2000, was inscribed to form part of the UNESCO World Heritage-listed Greater Blue Mountains Area.
