The tunnel systems at Hodge Close has long been a draw for divers. From what I recall from past experience theres one which does a loop and exits back into the quarry (there is a clear daylight zone here) the others unfortunately the scene of several fatalities either go off into the quarryside leading to dead end pardon the pun or dissappear into a labarinth with other off shoots.
Cave Diving and overhead environment techniques a must,
Andy will tell you the score
