Heading east from Imintji, it's only 25km to the Mornington turn-off and another 5km further to the entrance of Charnley River Station. If heading across the wild, lonely savannah to exquisite Mornington Wilderness Camp, call first using the radio at the Gibb. Back on the GRR, most of the cattle you pass are from Mount House Station. Cross the Adcock, wave to Nev and Leonie as you pass Over the Range Repairs, then drop down to Galvans Gorge at the 286km mark.
Fuel up at Mt Barnett Roadhouse, 300km from Derby, and get your camping permit if choosing to stay at nearby Manning River Gorge, though there are better options further east. There's free camping on the Barnett River at the 329km mark, and if you've still got daylight, consider pushing on to historic Mt Elizabeth Station, turn-off 338km mark.
