The Fortescue River in the City of Karratha is a significant waterway within the Millstream Chichester National Park, located approximately a two-hour drive south-east of Karratha. This section of the river is characterized by permanent, spring-fed pools that create a lush, tropical oasis contrasting with the surrounding arid landscape. A primary and popular paddling location is Deep Reach, also known as Nhanggangunha, a long, deep, and clear waterhole lined with paperbarks. Canoes, kayaks, and stand-up paddle boards can be launched here. The area is culturally significant to the Yindjibarndi people and is associated with the water serpent Warlu. The river and its floodplain provide a habitat for diverse wildlife, including numerous bird species such as rainbow bee-eaters, kingfishers, and raptors, with the possibility of spotting rare mammals like the northern quoll, particularly around dusk. The park offers camping facilities that must be booked in advance, especially during the peak winter season. While the river provides a sheltered, freshwater paddling environment away from coastal influences, a boat ramp is also listed at the river mouth, indicating potential for tidal or estuarine access. The best time for paddling is during the drier winter months, and the area is a photographer's and bird watcher's delight.
