You can find the canyon of death here.
27°26'6.35"S
153°32'44.76"E
I may go for a paddle and have a look, a line right near the entrance could be cool.
Only 70m or so.
I'm sure I can get a hold of some rope that long.
From the many pictures, it looks like you could walk the line across at low tide.
Maybe even able to rig a one way ride flying fox style.... |
