Karijini National Park is an Australian national park centred in the Hamersley Ranges of the Pilbara region in the northwestern section of Western Australia. The park is located north of the Tropic of Capricorn, 1,055 kilometres (656 mi) from the state's capital city, Perth.
At 627,422 hectares (1,550,390 acres), Karijini is the second largest national park in Western Australia (behind Karlamilyi National Park).
The park is most notable for its many gorges containing slot canyons, waterfalls and water holes with visitors sometimes swimming in the cold pools of water.
Hamersley Gorge is located in the northwestern region of the park, while Range Gorge is in the north, Munjina Gorge is in the east, and Hancock, Joffre, Knox, Red and Weano Gorges converge in the park's center.
While the park is fully open to the public, visitors are warned to exercise due caution when walking in and around the vicinity of Yampire and Wittenoom Gorges near the northern boundary of the park due to the presence of blue asbestos—a known cancer-causing agent when inhaled—which occurs in a number of the rock formations.
