Wittenoom town is the former site of asbestos mining and visitors should note the possible health risks of visiting the town. The southernmost town in the Pilbara is Onslow nestled on the coast off the main highway. Three National Parks have been established in the Pilbara to protect the natural wonders of the area. Hamersley Range National Park is one of Australia's largest reserves and within its borders lie some of the most ancient parts of the earth. A variety of gorges, each with its own peculiar features, exist within the Park which can be explored over a few days.
Camping is permitted in designated areas.
The dramatic landscape of the Chichester Ranges contrasts sharply with the permanent pools and tropical vegetation of Millstream. Ancient flora have survived the climatic changes over millions of years before the land became arid. Campsites are available in the Park and swimming is safe in the deep freshwater pools. Rudall River National Park is north-west of Newman off the Canning Stock Route.
