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: Only very experienced divers with overhead environment training should enter this dive attraction. Movement inside is restricted and the cold, darkness and depth can be very disorientating. If in doubt, DO NOT ENTER!
