Does anybody know anybody who can get access to the mines/caves in this area? I wouldn't mind a trip after work one day.
A few years back access was gained via Grosvenor Caving Club
- who supplied a leader for your trip (which is compulsory, as is insurance).
As for the caves - best bet is contact North Wales CC for current access info.
As Dan says, the Limestone workings are impressive, as is Powells Lode Cavern. Did a fine trip few years back - down OG and along main tunnel down to Powells Lode, then up an incline, along and back down some pitches to reach Barclays Lode, up and down into Powells Lode again and back along the tunnel out out via Limestone workings..
