More corrugated track, but managed to get to Windjana Gorge camp site around midday.
Quick set up and lunch and off to Tunnel Creek, about 30 minutes away. This was excellent; a river that flows underground for about 900m and in the dry season you can walk through using torches. Wide dusty tunnel with good stalegtites and stalegmites. You also need to wade through water above knee height (or if Vivienne you are carried). At the far end is a lovely water hole, then you walk back. Kids and adults alike enjoyed. Little cave off to the side had a beautiful stone waterfall.
Back at the campground the kids all played with other kids and were exhausted.
