Windjana Gorge

Windjana Gorge National Park is a 2,134-hectare protected area in the west Kimberley of Western Australia, centred on Windjana Gorge — a 3.5-kilometre gorge cut through the Napier Range by the Lennard River. The gorge walls rise 90 metres and expose 350-million-year-old Devonian reef limestone, creating one of the most spectacular geological and scenic experiences in the Kimberley. Windjana Gorge is famous for its population of freshwater crocodiles — up to 500 have been counted basking on the sandy river banks within the gorge. The park is managed by DBCA and Bunuba Dawangarri Aboriginal Corporation.

Windjana Gorge is WA's most accessible freshwater crocodile (Crocodylus johnstoni) viewing site — hundreds of crocodiles bask on sandbars within the gorge, providing an extraordinary wildlife encounter. Agile wallabies and wallaroos are abundant on the gorge floor and on cliff edges. Northern quolls inhabit the rocky terrain. Rainbow bee-eaters, blue-winged kookaburras, little corellas, red-tailed black-cockatoos, and sacred kingfishers are conspicuous. Flying foxes camp in fig trees along the river. At dusk, thousands of little bent-wing bats emerge from caves in the gorge walls.

The gorge floor supports riparian woodland of river red gums, freshwater mangrove (Barringtonia acutangula), paperbarks, and strangler figs (Ficus virens). The limestone cliff faces support lithophytic plants and fig trees in rock crevices. The plateau above the gorge is Kimberley savanna of Darwin stringybark and woollybutt woodland over tropical grasses. Australian boab trees (Adansonia gregorii) dot the landscape around the gorge, their swollen trunks storing water.

Windjana Gorge cuts through the Napier Range — part of the ancient Devonian reef complex approximately 350–375 million years old. The limestone walls of the gorge display fossil corals, stromatoporoids, brachiopods, and fish preserved in the reef structure. The Lennard River has eroded through the limestone along fault lines and weakness zones. The gorge is part of the same Devonian reef complex as Geikie Gorge, 100 km to the east. Both are World Heritage nomination sites.

Tropical monsoonal climate. The wet season (November–April) floods the gorge — the Lennard River becomes a raging torrent. The dry season (May–October) reveals the tranquil pools and sandbars where crocodiles congregate. Temperatures exceed 45°C in the build-up (October). The optimal visitor season is June–August.

Windjana Gorge (Bandilngan in the Bunuba language) is a place of profound significance to the Bunuba people. The gorge is associated with the spirit being Dumbi, who features in Bunuba law and ceremony. The gorge and surrounding range country was the theatre of Jandamarra's resistance movement in the 1890s — Jandamarra used the limestone range's cave network to evade police pursuit for three years. Bunuba rangers interpret this history for visitors.

Windjana Gorge National Park was proclaimed in 1971 and has been jointly managed with Bunuba Traditional Owners. The Bunuba Dawangarri Aboriginal Corporation plays an active role in park management, with Bunuba rangers operating cultural interpretation programs.

Windjana Gorge Walk — a 7 km return walk through the full length of the gorge, passing hundreds of basking freshwater crocodiles. Evening bat emergence — tens of thousands of little bent-wing bats exit cave openings at dusk. The Jandamarra cultural interpretation program with Bunuba rangers. Camping within the park.

Located on Fairfield-Leopold Downs Road, approximately 140 km from Derby via the Gibb River Road. Campground with powered and unpowered sites, toilets, showers, and kiosks. DBCA park entry and camping fees apply. Derby and the Gibb River Road scenic drive provide the primary visitor context.

Feral animals (pigs, goats, cats) degrade gorge vegetation and prey on native fauna. Cane toads are advancing through the Kimberley. The Napier Range limestone contains rare cave-dwelling invertebrates (stygofauna). Visitor management of crocodile approach distances is important for both visitor safety and crocodile welfare. Cultural site protection is managed by Bunuba rangers.
