Trail summary
Hike overview
Pack a picnic and get the family together for a great day out exploring Dharug National Park along Grass Tree circuit. This easy, undulating walking track starts near Mill Creek picnic area and meanders through rainforest and grass tree forest. It's a family-friendly bushwalking option near the Hawkesbury.
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.
If you've worked up an appetite, there are plenty of spots to spread out a blanket, spark up the barbecue or enjoy a leisurely picnic.
