A once-in-a-lifetime adventure. Walk across one of the most stunning deserts in the world – The Simpson Desert. If you are reasonably fit and are up for the challenge of a lifetime, this is for you! This will be a three-week trek.
Other trips include: The Wild Discovery Great Barrier Reef Adventure and Cape York by Land – Cairns to Cape York and Back
They claim “From catching feral camels to leading major treks and expeditions across the land, retracing early explorers and walking the deserts, we can organise anything at all”. More here
