We visited Karijini National Park. Access by 4WD vehicle – the one day tour organized by the agency from Tom Price is expensive but it takes full day and you drive almost 290 km. The gorges in Karijini are 100-150 m deep and very picturesque but suprisely narrow – do not expect anything like Grand Canyon. There are impessive, cool pools in the gorges you can swim – great experience in a hot day!
