Koolpin Gorge Kakadu

If your contemplating going to Kakadu, do yourself a favour and get permit to enter Koolpin Gorge. Permit is free just apply via the the Kakadu NP website.
When you get your permit you need to pick up the gate key from the Mary River Roadhouse ($50 deposit).
Drive north and turn of at the Gunlon Falls (Waterfall Creek) road when you get to the "Y" junction turn right and follow the signs. Once through the gate it is a slow 8km to the campgrounds.
There is 1 creek crossing and whilst not deep (about 400mm deep in early July) it is interesting as it takes a while to figure out where you exit the creek.
Collect firewood en-route as there is no firewood collecting around the campgrounds (officially).
When we were there there was only 4 other vehicles but you felt like you were alone. The campgrounds are well cleared with some shade trees. There is a composting dunny and BBQ and fire places are provided.
The water in the gorge is crystal clear and great for swimming in with stacks of fish to keep all amused. (no crocs either).
The walk up the gorge to the falls is a bit of a challenge as there is no formal track so the challenge is to find a path over all the boulders. At the end of the walk there are a couple of largish pools and a small waterfall.
Great fun place, great scenery and no maddening crowds. Don't forget the camera.
