Four-hundred-and-six kilometres from Derby you reach the Kalumburu turn-off. Head right on the Gibb River Road, and continue through spectacular country, crossing the mighty Durack River then climbing though the Pentecost Ranges to 579km where there are panoramic views of the Cockburn Ranges, Cambridge Gulf and Pentecost River. Shortly after is the turn-off to the lovely Home Valley Station.
Soon after Home Valley, at 589km from Derby, you'll cross the infamous Pentecost River – take care as water levels are unpredictable and saltwater crocs lurk nearby. El Questro Wilderness Park looms on the right. The last section of the Gibb River Road is sealed. The turn-off to beautiful Emma Gorge is 10km past El Questro. You'll cross King River 630km from Derby and, at 647km, you'll finally hit the Great Northern Highway – turn left for Wyndham (48km) and right to Kununurra (53km).
