Easy access here. The top to bottom through trip needs SRT, but the deep adit comes out just below the road.
Not sure how extensive the flooded areas are; and they're narrow stopes with timbers and ladders in. The most accessible one is probably the one just inby of the deep adit.
There are some bat sanctuaries in ByP, but I think this only applies September to end April.
my orders are to sit here and watch the world go by
