Australia's largest national park and a dual UNESCO World Heritage Site, Kakadu encompasses nearly 20,000 square kilometres of diverse landscapes—from tidal flats and floodplains to sandstone escarpments and monsoon rainforest. Home to one-third of Australias bird species and some of the worlds oldest Aboriginal rock art sites, including Ubirr and Nourlangie.
A Kakadu park pass is required. Check the park's access report before every trip, not just before the season: sites here close for months at a time — the Jim Jim and Twin Falls area is closed for all of 2026, and individual plunge pools shut whenever a crocodile is found in them. Many areas are unreachable in the wet, roughly November to April. Never swim outside a signed, open swimming area. Allow several days; distances between sites are long.
