It’s a true desert landscape in Nambung National Park, where the weathered rock spires of the Pinnacles rise out of yellow sand dunes.This is the Pinnacles Desert, a part of the Nambung National Park, roughly 200 kilometres north of Perth. Yet the park sits on the deep blue Indian Ocean, along an idyllic stretch of coast three hour’s drive north of Perth.These amazing natural limestone structures were formed approximately 25,000 to 30,000 years ago, after the sea receded and left deposits of sea shells.The Pinnacles remained unknown to most Australians until the 1960s, when the area was added to Nambung National Park. Today it receives over 250,000 visitors a year.
