Cahills Crossing
Crocodile spectacle at the causeway
schedule 1 min read / Updated Jun 2026
Cahills Crossing is a concrete causeway over the East Alligator River that marks the boundary between Kakadu National Park and Arnhem Land. From purpose-built viewing platforms visitors can watch saltwater crocodiles, some exceeding 4.5 metres, gathering in extraordinary numbers to feed on barramundi and mullet as the tide pushes fish upstream over the road.
The crossing hosts one of the highest concentrations of estuarine crocodiles found anywhere in Australia. Many crocodiles can be counted in the stretch between the causeway and the upstream boat ramp during peak season. The best months to watch are July through to October or November, reaching peak intensity from September onwards as the dry season concentrates wildlife and the tidal fish run is at its strongest.
Viewing platforms, a picnic area and a rainforest walking path make the site comfortable and safe for extended stays. Visitors must remain on the platforms and well clear of the water. Saltwater crocodiles carry high cultural significance for the Bininj people of the East Alligator region.
The site is accessible by 2WD vehicle and is located in the East Alligator region, close to the Ubirr turnoff. It is free to visit once a Kakadu park pass has been purchased. The viewing area is open year-round, though crocodile activity is most dramatic in the dry season.
