Serpentine Gorge, West MacDonnell National Park, Northern Territory.
This is Serpentine Gorge, a ~100m long, ~2m wide gorge that leads through to a beautiful canyon on the other side. Water was freezing, despite the 38C air temperature. We floated through on lilos, as we had a bit of gear to get through to the other side. Saw a perentie while in the water here.
