if you follow the road all the way down did you come across some pretty big gates, if so you've gone to far, the way we went in was just up the hill as you turn in on the left hand side only about 50ft from the entrance it leads down into the quarry on the left, if i can figure out how to upload some pics i will put them up in my gallery. i will be back down that way on sunday the 2nd sept if you fancy meeting up, if the weather is ok tomorrow, two mates from rhyl will be there
