This is one of the must see places if you visiting Perth. An important tourist destination, about 2 - 3 hours from Perth downtown.
As you vast dry lands by the ocean, the landscape changes dramatically and you start seeing thousands of limestone pilars / mounds formed by the vagaries of weather, wind & rain.
We also got to enjoy packed dinner in the midst of sand dunes and watch stars with a portable telescope.
We took an arranged day trip from one of the popular tour operators who picked & dropped us back at our Hotel. Though, we found the tour package little pricy, it was worth it given it was guided and we needn't have to drive.
