The Kimberley region's really quite rugged but absolutely beautiful if you do a 4WD self-tour. There are various 4WD trails of different difficulty to choose from and do the necessary research before you embark on this adventure. It can be REALLY FUN, driving through rivers and stuff especially around Fitzroy Crossing, but do note that if you get stuck, the fun may all end there. Have some form of satellite communication if you know you're going deep into the outback and have loadsa water, fuel and other supplies. DON'T try to navigate the Canning Stock Route unless you're a really really really seasoned 4WD-er or super 'garang'. You need to arrange fuel-drops by air in advance and have sufficient planning.
