 North of Carnovon , the highway passes through desert and becomes very flat . Bridges span many ephemeral rivers and creeks , with strands of eucalyptus along their floodplains . The next roadhouse , 135 kilometres ( 84 mi ) beyond Carnovon , is the Minilya Roadhouse adjacent to the Minilya River . Seven kilometres ( 4 @.@ 3 mi ) further on is the turnoff to the North West Cape area , including Cape Range National Park , Coral Bay and Exmouth .
