Keith with the assistance of Brendan navigating found the mine this time. (Last time we failed to find it - both believing that the other one knew where it was!) A 400 foot ladder climb led us down into the tunnel, to breath in the diesel and smoke fumes from the recently departed train. (An audible sob was heard to escape from Keith.)
We then headed to the limestone working where we spent about 4 hours taking photos in some of the larger galleries. We then headed out via the upper limestone workings.
