Nice place to visit, not much to see, but easy enough to get to. I did have a farmer watching me walk up the path, but nothing come of it,

This was the first of 2 slate mines/quarry's that i visited this weekend, the scenery blew me away at this place as much as the explore itself, plenty to see here with all the old slate buildings pump houses etc, big lake itself is used by divers and hides alot of the good stuff, the lake is up...
