Murchison River Gorge

The Murchison River has cut an 80-kilometre gorge through red-and-white banded sandstone laid down on tidal flats some 400 million years ago — its exposed layers among the most accessible places on earth to read the trackways of some of the first animals to walk on land. Nature's Window, a wind-eroded arch, frames the river at the head of the 9km Loop walk; Z Bend marks its sharpest turn. Nanda Country, in Kalbarri National Park.

Flash flooding can occur with little warning, especially in the wet season. Check weather forecasts before entering gorges. Wear sturdy footwear with good grip on rock surfaces. A moderate level of fitness is recommended. Bring adequate water and wear appropriate footwear.
