If you park by the pub (you need the landlord permission to park ON the pub car park - a Mr Tomos), there is flat walk of aeound300 yards, then a short steep uphill (50 yards) (assuming you find the path).
First ladder 30 feet, 50 yards into mine, 2nd ladder 10 feet (and a little squeezy but ok). Third ladder almost immediately and drops 30 feet, 50 yards walk, another ladder 10 feet, short, roped assisted "slope" (not an incline), ladder 10 feet.
Then, immediately, a series of three ladders together (60-80 feet in total).
At the base of the ladder, ignore the water in front of you under the broken bridge and go into the tunnel underneath the ladders.
30 yards then (keep right) two holes down to the water (the second on is better).
The water level is currently near the top of these but in dry weather it drains down about 60 feet. At the moment, you will need to "dive down" this flooded slope about 50 feet to find the level.
When you hit the level, going left takes you to the next incline down (which had a divers line) and going right takes you to the elusive workings we saw briefly when the whole level drained.
