Hidden in dense scrub and reached via a tough bush-bash up from the Bairne Track, it’s hard to imagine that not so long ago there were great views from here. In 1899, W.D. Campbell wrote “The hill being bare of trees a very fine view of Pittwater can be obtained from here” and in the 1970s a National Parks brochure stated there were “excellent views from Bairne Trig”.
The trig station itself is well preserved, with the still-intact vane standing on top of a very solid rock cairn.
The best approach is from the Bairne Track, leaving the track around 33°36’44.1″S 151°17’06.2″E. Expect some sections of thick scrub, as well as some large rock platforms (stay on these as much as you can).
