Stone Delivery Tunnel
14m-22m
For the more experienced visitor to Vobster Quay, we offer the Stone
Delivery Tunnel - an 18m long tunnel cut through the lime stone back in
the days when the quarry was still operational. Despite being
reinforced with a concrete liner along its entire length and wide
enough for three divers to travel through side by side, the tunnel
should only be attempted by those divers with overhead environment
training - even then, only enter if you like your overhead environments
dark and spooky!
The
entrance to the Stone Delivery tunnel can be found at the end of the
track that leads from the quayside slipway. Lying at a depth of 14m,
you'll find a thick white cable tied off at the entrance to the tunnel.
Running along the roof for the entire length of the tunnel, this cable
provides a useful guide line for even the most experienced overhead
environment diver. As you progress through the tunnel, the depth will
steadily increase until you reach the exit at 22m.
At
the tunnel exit, you'll find yourself very close to the Crushing Works.
To locate the Crushing Works from the tunnel exit, follow the wall on
your right hand shoulder for approximately 5m.
SAFETY FIRST - This attraction should only be entered
by divers with overhead environment training. The tunnel is very dark
and can be very disorientating! If in doubt, DO NOT ENTER!
