Nambung National Park

Listen to the sand first. It squeaks a little under your shoes, fine and pale yellow, almost warm even in the shade. The wind comes in from the Indian Ocean, and it carries salt and the dry smell of coastal scrub. Then look up. All around you, rising out of the dunes, stand thousands of stone pillars. Some reach only to your knee. Others tower well over your head. This is the Pinnacles, the heart of Nambung National Park.

The park sits on the coast of Western Australia, roughly two hundred kilometres north of Perth, close to the small fishing town of Cervantes. Most visitors drive up the coastal highway in a couple of hours. The landscape changes slowly on the way, from farmland to low heath to bright sand. When you finally arrive, the Pinnacles Desert feels sudden. It is like walking onto another planet, yet it is only a short walk from the sea.

So what exactly are you looking at? These pillars are limestone. And that limestone began as life in the ocean. Over a very long time, shells and the remains of tiny sea creatures were broken down and washed ashore. The wind carried this lime-rich sand inland, and it piled up into dunes. Rain then soaked through the dunes. It dissolved some of the lime and cemented the sand below into hard rock.

How did that rock become separate columns? Here the scientists do not fully agree, and that is part of the fun. One idea is that plant roots and cracks guided water down certain paths. Some areas hardened more than others. Later, the softer material eroded away, and the wind blew the loose sand off. What stayed behind were the tougher cores — the pillars you see today. Each one is a record of water moving through stone.

Here is something many visitors miss. The Pinnacles are not fixed in place. The dunes are always moving. Strong winds can bury some pillars and uncover others. So the desert you see today is not quite the desert someone saw fifty years ago. A pillar that stands tall this season could be half-covered in sand within a few years. Look closely at the base of the columns, and you may see the line where the sand has recently shifted.

For a long time, very few outsiders knew this place existed. There is a popular story that Dutch sailors passing this coast in the seventeenth century saw the pillars from the sea and thought they were the ruins of an ancient city. It is a lovely image, but treat it as a tale rather than firm history. What is clear is that the Pinnacles became widely known to travellers only in the second half of the twentieth century.

Of course, this land was known long before any sailors appeared. Nambung lies within the country of the Noongar people, the Aboriginal people of southwestern Australia. Their connection to this coast reaches back many thousands of years. The name Nambung itself is usually explained as a local Aboriginal word meaning crooked or winding. It refers to the Nambung River, which runs through the park and then disappears underground into the limestone.

Now, take a moment to look at the colours. The sand here is a golden yellow, and the pillars range from pale cream to rust and grey. Many columns have a rough, pitted surface. Some are smooth and rounded at the top, while others end in sharp points. A few even look like faces or animals, depending on where you stand. Walk slowly around one pillar, and its shape will change with every step.

The light changes everything here. In the middle of the day, the sun is harsh and flat, and the shadows almost vanish. But early in the morning and late in the afternoon, the pillars cast long shadows across the sand. The yellow turns deep orange, and the stone glows. If you can, stay for sunset. And after dark, the sky above this quiet coast fills with stars, far from the lights of the city.

You may not be alone out here. Western grey kangaroos often graze around the edges of the desert, especially in the cooler hours. Emus sometimes walk through the scrub with their slow, careful steps. Listen for small birds, too — honeyeaters feed on the flowering shrubs around the park. If you visit in late winter or spring, the heath around the Pinnacles can fill with wildflowers in yellow, purple and white.

There are two main ways to explore. A one-way unsealed drive winds slowly between the pillars, with places to pull over. Or you can leave the car and follow the walking trail, which brings you right in among the columns. Walking is the better choice if you have time. The scale feels very different on foot. Near the entrance, a discovery centre explains the geology and the wildlife of the area.

The park is not only the desert. Its western edge meets the Indian Ocean, with white beaches and calm bays where families picnic and swim. Places like Hangover Bay and Kangaroo Point offer a very different mood — blue water instead of yellow sand. Just outside the park, near Cervantes, you can also find Lake Thetis. Its shallow waters hold stromatolites, rock-like structures built by microbes, which are among the oldest forms of life on Earth.

Please remember that this is a fragile place. The pillars may look solid, but they can break. Climbing on them causes damage that will not repair itself. Stay on the paths, and take only photographs. Bring plenty of water, because the sand reflects heat and the shade is limited. Sun protection matters here in every season. And watch for the small flies in summer, which can be very persistent.

Before you leave, stand still for one more minute. Feel the wind on your face and the soft sand under your feet. Look at the nearest pillar and think about where it came from — shells from the sea, rain from the sky, and a very long stretch of time. As you walk back, notice how the shadows have moved since you arrived. The desert is changing, slowly, even as you watch.
