Use the lower car park at Hamersley Gorge, off Nanutarra-Wittenoom Road, then take the separate steep descent to the waterfall. The lower parking area is reached by sealed road and has a toilet and lookout. Published distances for that approach differ, so the 400 m Spa Pool figure is not the full walk from the car park. Access advice for the upper pools conflicts: a current description of the waterfall walk says not to attempt them, while the visitor guide lists Spa Pool separately as Class 5. Check current access with park staff and obey signs before continuing upstream. Karijini's gorge water can be extremely cold, especially April to September; flash floods can occur, so leave the gorge if rain starts. Dogs are not permitted, except certified assistance animals.
