Entrance to Glow Worm Tunnel, Gardens of Stone National Park
The second tunnel is a walking tunnel. Take a torch, the tunnel floor is wet and very rough and not far in it's pitch black.
Sorry, no photos of the glow worms. I don't know how to take photos of pin pricks of light in deep dark black.
Words to walk with:
A Clear Midnight by Walt Whitman
This is thy hour O Soul, thy free flight into the wordless,
Away from books, away from art, the day erased, the lesson done,
Thee fully forth emerging, silent, gazing, pondering the themes thou
Night, sleep, death and the stars.
