Kakadu National Park
Australia's best known national park is located 200 kilometres east of Darwin. The name Kakadu is derived from Gagadju, one of the several languages of the Aboriginal people of the district. A world Heritage Listed National Park, Kakadu is one of the few regions in Australia where the original inhabitants maintain personal and spiritual links with their traditional lands. The park is loaded with rock art sites and the most famous is Ubirr. A good guide will direct you to the many famous locations. Try Kakadu Dreams for 3 and 5 day tours.
The southern part of the park is less developed and more rugged than it's counterpart to the north. This natural habitat abounds with saltwater crocodiles and there is an abundance of birdlife. The rivers overflow with Barrumundi, a local fish that is delightful.
Beware of the Crocs!
During the wet season the park's many waterfalls come alive and if you can stand the weather, they are worth a look. There are many tours and camping safaris available . This is a highly organised park. Accommodation is limited so be prepared.
My advice for this one is to seek the help of guides and the local tourist authorities. They know the park and you will get to see the park from an expert's view and not miss any highlights.
