Last full day in Australia so took a trip down to Litchfield National Park a hundred KM south of Darwin. We stopped on the way down at the Adelaide River to see the famous jumping Crocodiles. And jump they certainly do. The trip is amazing. You take to the water in a small 40 seat boat and set off down the Adelaide river. It all seems so peaceful, just the place for a swim, until you notice a dark shape heading towards the boat like an exocets. It all gets very surreal then as the boat driver dangles a pork chop on a fishing line over the side of the boat and suddenly this monster is alongside the boat snapping and leaping until it can twist its jaws around the meat. It's like going through a theme park and difficult comprehend that the enormous reptile alongside the boat is not some anamotronic put there to please the crowds, but a killing machine looking for food. We saw two massive males, both over 5 meters long, and several smaller females. Very exciting. In the afternoon we visited some waterholes where you could actually swim, they were high enough in the hills that they were croc safe.
