The mystery of the fictional book and film "Picnic at Hanging Rock", evolves around the disappearance of several school girls in the 1900's on a picnic at Hanging Rock in Victoria, is still talked about by people who come to climb the rocks.
The story may not be true, but you certainly can loose each other easily with all it's twists and turns.
The stuff kids love.
Crawling through tunnels, clambering up and over boulders, and having a real adventure.
We ourselves enjoyed a picnic at the top.
