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 ๐
And not mentioned by Yuri Bolotin
in Walk.18 in the book
"Gardens of Stone National Park and Beyond"
(by Michael Keats & Brian Fox)
Just curious ๐ ...
- Has anyone been to this cave / tunnel ?
- Were we the first group here ?
