Apple Tree Bay Birrawanna Loop is a 3.9km, grade 4 Circuit hike located in Ku-ring-gai Chase National Park New South Wales. The hike should take approximately 2 hrs to complete.
This walk enjoys some great views and quiet bushland in Ku-ring-gai Chase National Park. From Apple Tree Bay the walk soon heads over the hill and loops down to Bobbin Head with the option of a bite to eat at the kiosk before returning along a similar but different route to Apple Tree Bay. The walk has some steep sections but is well worth the effort.
