Hike overview
A visit to Waa Gorge doesn't need to end with its picnic area. Indeed, this is only the beginning: from here, you can explore the nooks and crannies of the ancient formation. Mill-bullah walking track offers a good introduction, finishing at the beautiful Mill-bullah waterholes. 'Mill-bullah' means 'two eyes', and nearly anybody can see them on this medium-grade path along a shady creek.
Start your walk near the information shelter, which provides a fascinating insight into the box-cypress forest and dry rainforest of the area. The track from here is just 500m long, so it's suitable for most visitors. For the best experience, visit in spring or autumn, when temperatures are cool, and bring some binoculars for a bit of birdwatching along the way.
From the Mill-bullah waterholes, experienced walkers can continue on to Waa Gorge through Grattai Wilderness Area by taking Waa Gorge walking track.
