World Heritage-listed Kakadu National Park is a landscape of contrasts. Beneath waters dotted with lotus flowers, saltwater crocodiles lurk, jagged peaks of towering escarpments hide pockets of monsoon rainforest and waterfalls cascade into pools fringed with paperbarks, pandanus and cycads. Travellers can view the spectacular Jim Jim Falls, browse through a gallery of ancient Aboriginal rock art at Ubirr or Burrungui / Nourlangie Rock, or explore the scenic Yellow Water, a billabong teeming with wildlife. An entry fee applies to enter Kakadu National Park. Kakadu is shaped by water, being the catchment area for the South Alligator, East Alligator, Katherine, Roper and Daly rivers. From November to May, waterfalls are at their most spectacular and the lowlands are flooded, attracting millions of migratory birds. The unique and diverse avian life in Kakadu includes jacanas, azure kingfishers, cuckoos, rufous owls, magpie geese, jabiru and more. Travellers have several accommodation options in Kakadu, ranging from campsites to hotel accommodation. Further east lies Arnhem Land, encompassing 91,000 square kilometres of unspoiled wilderness. This land harbours a rich and ancient Aboriginal culture and is home to many Aboriginal people, many of whom continue to practise the traditional way of life. The natural beauty of areas such as Gunbalanya / Oenpelli and Mount Borradaile, and the endless coastlines of the Nhulunbuy / Gove and Cobourg Peninsula, make venturing into Arnhem Land unforgettable. These coastal areas are also excellent fishing destinations. Travellers wanting to visit Arnhem Land need to apply for a permit from the Northern Land Council, or if visiting on a tour, these are organised for you.
