The Rudall River, known as Karlamilyi in the local Wanman language, is an ephemeral river flowing through the heart of Karlamilyi National Park in Western Australia's Pilbara region. It is a remote and rugged watercourse, characterized by its intermittent flow and the presence of deep, permanent pools that sustain life through the dry periods. The river traverses the largest and most remote national park in Western Australia, creating a landscape of immense scale and isolation. Access is challenging, requiring significant preparation and a capable four-wheel drive vehicle, making it a destination for experienced adventurers seeking solitude and a connection with a truly wild Australian environment.
