Attraction Information



A twinset diver swims up through the tunnel following the guideline on the roof...

The tunnel is concrete-lined throughout so navigation is relatively easy...

A high-visibility guideline runs along the roof and is tied off at either end...
For the more experienced diver with overhead training, we offer the Stone Delivery Tunnel - an 18m long concrete-lined 'cave' cut through the limestone 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!

Located at a depth of 14 metres, the entrance to the tunnel can be found at the end of the track that leads down from the quayside slipway. Once you reach it, you'll discover a thick white cable tied off at the entrance. Running along the roof for the entire length of the tunnel, this high-visibility cable provides a useful guideline for even the most experienced overhead environment diver.

As you progress through the tunnel, be aware that the depth will steadily increase until you reach the exit at 22 metres. Visibility and ambient light levels can varying massively between the entrance and exit to the tunnel so make sure you that you keep your torch switched on even once you've exited the tunnel. We recommend that any diver entering the tunnel carries at least *two* torches.

At the tunnel exit, you'll find yourself very close to the base of the Crushing Works. To locate the Crushing Works from the tunnel exit, fin forward with the wall on your right hand shoulder for approximately 5 metres.
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!

Fancy seeing something different in the dark? This Thursday our friends from Linear Guidance Illumination - LGi will be at Vobster Quay Inland Diving Centre demonstrating their illuminated marker systems. Used by the police and the military, as well as many commercial organisations, maybe this is how we should mark out all our routes and features for safer low-light and dark diving conditions? Come along and see what you think! Cheers, Pete
