Karijini National Park is located in the Pilbara region and features ancient cavernous gorges and some of the oldest rocks on Earth. It is a naturalist's dream, and some of the experiences that can be enjoyed at the park include swimming in a natural spa pool at Hamersley Gorge, taking photographs of the majestic scenery in Oxer Lookout, and going on a tour of Hancock Gorge that'll take you on a steep descent into multi-coloured layers of rock.
