Australia
Karijini National Park
Swim through gorges of banded iron two billion years old, their walls striped like geological barcodes.
The gorge walls are striped in bands of red, blue, and gold — banded iron formation laid down 2.5 billion years ago when the Earth's atmosphere had no oxygen. You swim between them, the water cold and clear, your fingers trailing across rock that is half the age of the planet.
Karijini National Park in Western Australia's Pilbara region contains some of the oldest exposed rock on Earth — banded iron formations deposited in ancient seas 2.5 billion years ago. The park's gorges — Hancock, Weano, Joffre, Knox — are accessed by scrambling, swimming, and squeezing through narrow chasms where the walls are close enough to touch with both hands simultaneously. Fern Pool, at the base of a waterfall in Dales Gorge, is a permanent swimming hole framed by termite mounds and paperbarks. The geological significance of these rocks is global — the banded iron was laid down by cyanobacteria producing the oxygen that would eventually make animal life possible.
Solo
Gorge scrambles that demand full physical attention — Karijini rewards solo adventurers who are comfortable with their own capability.
Couple
Swimming together through 2.5-billion-year-old gorges, then eco-tent glamping under Pilbara stars — geology and intimacy combined.
Friends
Spider walks, rock slides, and plunge pools — Karijini's gorges are a natural obstacle course that groups tackle together.
- Gorge walls of banded iron formation are 2.5 billion years old — half the age of the Earth itself.
- Swimming through narrow gorges where the walls nearly touch, striped in red, blue, and gold iron oxide.
- Spider walks and rock slides lead to plunge pools hidden deep inside the gorge systems.
- Eco-tents at the gorge rim offer hot showers and beds after a day of gorge exploration.
