Plunging over the edge of a columnar basalt lava flow, Big Millstream Falls is reputedly the widest single-drop waterfall in Australia. Wander down the walking track leads to spectacular views of the falls.
A separate entrance to the park leads to Little Millstream Falls. Take in their long plunge from just near the car park, or get up close by taking the steep and narrow track to their base.
The park has a rich World War II history. Step back in time to the early 1940s, when the Tablelands were dotted with training areas for up to 100,000 Australian troops. You can follow the World War II heritage walk and see the remains of the camp sites that were constructed for the Battalions of the 7th and 9th Divisions between 1943 and 1945. See the remains of tent sites, corduroy roads, training and parade grounds, trenches and other reminders of the time spent here.
