An Australian Outback Adventure and a great icon, the well maintained, unsealed track links Birdsville in Queensland's south-west to Marree in the mid-north of South Australia. The Birdsville Track covers some of Australia's most beautiful and challenging country, passing through the Simpson Desert and Sturt's Stoney Desert. Lake Eyre catchments, wetlands, sand dunes and vast gibber plains. Track conditions are rough and challenging. The surface is generally extremely dry on a sandy base covered with gibbers. Travelling speeds vary depending on conditions and your load. The track will take its toll on tyres and travellers in four wheel drive vehicles are in a much better position to handle the terrain and minimise breakdowns and tyre punctures. Travellers should carry water and supplies in case of emergencies.
