The tiny township of Adelaide River, about 115km south of Darwin, is best known as the home of Charlie the Buffalo, who starred in the movie Crocodile Dundee. (He’s now deceased, but taxidermied Charlie graces the bar at the Adelaide River Inn). Not far from here, you'll find one of the best places to cool off in the Northern Territory. Robin Falls remains very much under the radar, and the trail is not particularly well kept: in places you'll have to scramble over a few rocks. However, these three-tiered falls are definitely worth the journey.
