We went to Big Yango in
Easter 09, road had just been graded, we took a Range Rover, a Territory with Windsor Rapid, Disco with Rapid, Pajero with Rapid and a Prado. The Parks guys are a great help, there is some fantastic
rock art that is hidden so ask the parks guys they may show it to you. Its a bit expensive but there are not many hidden spots left it the parks,
Well worth the trip.
