From the Kalumburu Rd it's a rough 87km, past lookouts and forests of livistona palms to the park's dusty campground. Leave early if walking to Punamii-unpuu (Mitchell Falls; 8.6km return). The easy trail meanders through spinifex, woodlands and gorge country, dotted with Wandjina and Gwion Gwion rock-art sites, secluded waterholes, lizards, wallabies and brolga.
The falls are stunning, whether trickling in the Dry, or raging in the Wet (when only visible from the air). You can swim in the long pool above the falls, but swimming in the lower pools is strictly forbidden because of their cultural importance to the Wunambal people. Most people will complete the walk in three hours.
