Ikara-Flinders Ranges National Park

Ikara-Flinders Ranges is the most readable landscape in South Australia. The rock here records several hundred million years of sedimentary history, tilted and eroded until the layers sit exposed at the surface where you can drive alongside them.

Wilpena Pound, or Ikara, is the feature everyone comes for: a natural amphitheatre ringed by a continuous ridge, roughly 17 kilometres long. It looks like a crater and is not one. It is the eroded remains of a fold.

Access and roads

The sealed road runs to Wilpena, so getting to the main resort area and campground is straightforward in any vehicle.

Everything more interesting is gravel. Brachina Gorge, Bunyeroo Gorge and the Moralana Scenic Drive are unsealed roads with creek crossings, and they range from smooth to badly corrugated depending on when they were last graded and how much rain has been through.

None of it is technically difficult four-wheel driving in dry conditions. All of it is unpleasant and slow at highway tyre pressures. This is gravel touring rather than off-roading, and the main thing it asks of you is that you slow down and let the pressures down.

After rain, the creek crossings change character quickly and some roads close.

The Brachina Gorge Geological Trail

This is the standout, and it is genuinely unusual: a self-drive route with numbered interpretive stops, each one marking a different geological formation, arranged so you drive forward through deep time.

It works because the sequence is exposed and continuous. You are not looking at an interpretive sign describing something invisible. The rock is right there at the roadside.

The trail includes the Golden Spike, the internationally ratified reference point for the base of the Ediacaran period. It is a marker on a hillside in a gorge in South Australia, and it defines a division of the geological time scale worldwide.

Yellow-footed rock-wallabies live along the gorge and are most active early and late.

Camping

Wilpena Pound Campground is the large, serviced option, with powered sites, showers and a shop.

The bush camps scattered through the park along the gorge roads are the better experience if you are self-sufficient: small, unpowered, mostly a cleared area and a drop toilet. They book through the state parks system and cost little.

When to go

April to October. Winter days are mild and the light through the ranges in the hour after dawn and before dusk is the reason photographers keep coming back. Nights get cold and frost is common.

Summer is hot enough to be genuinely limiting, with temperatures regularly through the high thirties and into the forties.

Country

The Flinders Ranges are Adnyamathanha country, and Ikara is the Adnyamathanha name for Wilpena Pound. The park is co-managed, and the Adnyamathanha account of how the Pound formed is presented alongside the geological one at the visitor centre.
