2026 July 12 ... day-hike

To  Invincible Trig  (Ben Bullen)
      Invincible View Cave  (GOS)
      Signature Cave  (GOS)

in  Ben Bullen State Forest  &
     Gardens of Stone State Conservation Area
     NSW, Australia




This trip report -
Cave / tunnel beneath Invincible Trig


This report is only on the cave / tunnel
just beneath Invincible Trig
in Ben Bullen State Forest.






It is a cave with 2 openings ... like a tunnel.

The cave can't be seen from the trig area,
because it is over the cliff edge.

It is not documented anywhere on the web ...
Except here 😊

And not mentioned by Yuri Bolotin
in Walks 5.18 in the book
"Gardens of Stone National Park and Beyond"
Book 5
(by Michael Keats & Brian Fox)




Just curious 😊 ...

- Has anyone been to this cave / tunnel ?
- Were we the first group here ?
