Mary River National Park, Nature reserve in Northern Territory, Australia
Mary River National Park is a protected landscape in the Northern Territory that combines wetlands, woodland, and floodplain habitats. The terrain is dominated by water channels and low-lying land that transforms with the seasons.
The park was created in 2007 by merging thirteen separate protected areas along the Mary River, the McKinlay River and the Arafura Sea coast. These included the Mary River Conservation Reserve, the Point Stuart Coastal Reserve and the Stuart Tree Historical Reserve. The park is reached via the Arnhem Highway.
The park's name comes from the Mary River, one of eight Top End rivers with wide floodplains; the Arnhem Highway crosses five of them between Darwin and Jabiru. The former Stuart Tree Historical Reserve, now part of the park on the Arafura Sea coast, marks a site tied to explorer John McDouall Stuart's 1862 crossing of the continent.
The best time to visit is during drier months when roads and paths are easier to access. Visitors should prepare for uneven terrain and bring water and sun protection for outdoor exploration.
The park is home to saltwater crocodiles that can be spotted during river tours. These powerful predators are a sign of the region's untamed natural environment.
