Windjana Gorge National Park, Nature reserve in Kimberley region, Western Australia.

Windjana Gorge is a canyon with limestone walls that rise up to 30 meters high, cutting through the landscape for several kilometers. The Lennard River flows through the gorge and creates permanent pools where wildlife gathers.

The gorge cuts through the Napier Range, a Devonian reef system more than 375 million years old. The reef was uplifted about 250 million years ago and later buried by sediment; a second uplift around 20 million years ago exposed the limestone built by algae, stromatoporoids and corals. The Lennard River then carved the present gorge.

The Bunuba name the gorge's creation spirits Wandjina; William Forrester, who set up a farm here in 1884, misheard this as Windjana. The Bunuba resistance leader Jandamarra was shot at Pigeon's Rock on 16 November 1894, escaped to Tunnel Creek and hid there for 2.5 years. The ruins of the Lillimilura Homestead, later a police station, remain.

Access is via the unsealed Gibb River Road and Fairfield Leopold Downs Road, with a 20 km spur into the park; the park is closed in the wet season when tracks become impassable. A marked walking trail follows the river to the upper end of the gorge, about 7 km return. Start early because it is hot even in winter, and bring your own firewood for the campground, where a ranger collects fees in the evening.

Freshwater crocodiles have adapted to human presence in the gorge and coexist alongside visitors in the permanent pools. These reptiles are generally shy and keep their distance while maintaining their natural behaviors.
