Blocked by falls, and ropes needed to get there.
It’s a familiar tale, the Wheal Edward incline shaft to the south west is the same.
Accessible working from Pendeen going south west
Wheal Hazard, accessible from shore, tide discipline. Climb down under lower Crowns engine house.
Grylls Bunny, easy
Cargodna Adit, descend what used to be Looe Warren, bear left, rope for final drop to shore. Cuts Cargodna Shaft
Wheal Edward upper adit, 20 foot SRT to workings, more SRT if you have death wish
Wheal Castle, canoe or path of death leading to 50 foot of rope work then a climb up. Not worth effort.
Porth Ledden, steel ‘gated’ adit leads to dodgy climb up, best done from other entrances
Ditto, climb up to adit driven in 1910, connected with Cape Cornwall mine, currently blocked by fall, I think.
Cape Cornwall Mine (Out on cliffs, southern flank of Cape Cornwall) Bricked up and a difficult climb to reach it anyway
Priests Cove. Several open adits, main one leads into workings to emerge on other side, see above.
Should be enough here to keep you going.
My avatar is a poor likeness.
