Without a doubt, the Jumping Crocodile Cruise is one of the things you can't miss in Kakadu. We're talking about saltwater crocodiles (also called estuary crocodiles) and lovingly called "salties" in Australia. Normal crocodiles, like the ones in the Nile, only live in fresh water but these massive Australian beasts also live and swim in the ocean. They can often appear in coastal estuaries but their favorite habitat is the coastal rivers. The one catch is that humans are not off the menu for these enormous reptiles and attacks are more frequent than we'd like the think. Your best bet is to pay attention to the warnings you can see in the river areas.
