Karijini National Park is a National Park centred in the Hamersley Ranges of the Pilbara region in northwestern Western Australia (Australia). It is just north of the Tropic of Capricorn, approximately 1,055 kilometres (656 mi) from the State's capital city, Perth. Formerly known as Hamersley National Park, it was renamed in 1991.
At 627,442 hectares (1,550,440 acres), it is the second largest national park in Western Australia (Karlamilyi National Park is larger). The park is physically split into a northern and a southern half by a corridor containing the Hamersley & Robe River railway and the Marandoo iron ore mine. The park is served by the Solomon Airport, located 15 kilometres (9.3 mi) westwards.
The park is most notable for its four prominent gorges marked by waterfalls and water holes. Klein Crater is not part of the national park but is due south of the national park, just off the Great Northern Highway.
The park's wildlife includes red kangaroos, euros, wallaroos, echidnas, geckos, goannas, bats, legless lizards and a large variety of birds and snakes, including pythons.
While it is still fully open to the public, visitors are warned to exercise due caution when walking in and around the vicinity of Yampire Gorge (situated near the northern boundary of the park) due to the presence of asbestos in a number of the rock formations.
