Heading east from Broome, the Great Northern Highway (GNH) traverses the flat, scrubby Roebuck plains before crossing the (sometimes) mighty Fitzroy River at Willare Bridge, just before Derby. Boab-lined Derby makes a pleasant overnight stop while you decide whether to take on the legendary Gibb River Road or sample the bitumen delights of the GNH for the next 900-odd kilometres to Kununurra.
The Gibb (4WD, dry season only) provides access to the majestic Mitchell Falls, far-flung Kalumburu and the beautiful hidden gorges, eroded ranges and sweeping savanna of the Kimberley interior. The bitumen, all-weather GNH runs further south and connects the remote Kimberley towns of Fitzroy Crossing and Halls Creek. It's also the access route to the sublime Bungle Bungle Range of Purnululu National Park and the Devonian Reef National Park and is the jumping-off point for trips south into the sparsely populated Tanami.
