Look up into the trees for cackling kookaburras, tiny fairy wrens and honeyeaters. This is also home to the shy lyrebird, although you’ll have to be quiet or you’ll scare them into the undergrowth. There’s also a chance you’ll see a goanna or two, sunning themselves on nearby rocks.

Best times to visit

There are lots of great things waiting for you in Dharug National Park. Here are some of the highlights.
The water has warmed up nicely by late summer so autumn is great for kayaking and canoeing along the Hawkesbury river.
The spring months are perfect for enjoying more strenuous activities in the park, like the longer walks and mountain bike riding. It’s also the perfect time to see wildflowers.
The park is still stunning in winter and walking on sunny days is very pleasant. It can be cold at night so bring warm gear if you’re camping.
