Pinnacles desert is situated from the coast of southwest Australia are thousands of limestone pillars that rise from the shifting yellow sands. This is the Pinnacles Desert, a part of the Nambung National Park, roughly 200 kilometres north of Perth. These amazing natural limestone structures were formed approximately 25,000 to 30,000 years ago. The Pinnacles desert 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. The best season to see the Pinnacles is spring from August to October, as the days are mild and wildflowers start to bloom. The pinnacle formations are best viewed in the early morning or late afternoon as the play of light brings out the colors and the extended shadows of the formations delivers a contrast that brings out their features.
