Fodor's Expert Review Jim Jim Falls
The best way to gain a true appreciation of the natural beauty of Kakadu is to visit the waterfalls running off the escarpment. Some 39 km (24 miles) south of the park headquarters along the Kakadu Highway, a track leads off to the left toward Jim Jim Falls, 60 km (37 miles) or about a two-hour drive away. The track is rough and unpaved, and you'll need a four-wheel-drive vehicle to navigate it. From the parking lot, you have to scramble 1 km (½ mile) over boulders to reach the falls and the plunge pools they have created at the base of the escarpment. Note that after May, the water flow over the falls may cease, and the unpaved road is closed in the Wet.
The best way to see these falls at their best is on a scenic flight from Jabiru during the wet season (from A$250 per person for an unforgettable one-hour trip).
