The Copper Kingdom Centre, Amlwch Port, Anglesey, LL68 9DB
Definitely worth a visit, some people also call the mine – Parys Mountain
Was of Hope Mountain:
Here are some more pics of Hope Mountain
To get up there – park in Caergrwle car park. Walk out of the exit (on the right as you enter), then turn left.
You can follow your nose and head straight up the street right in front of you, and there is a small stile you jump over – this way is VERY overgrown, but bloody awesome.
Alternatively you can come out of the car park, turn left and then turn left again and follow that road all the way up into what appears to be a cul-de-sac of houses. However, on the top right, there is a path you can follow, and turn left off of about 100m of the way up.
Finally, if coming from Wrexham towards mold on the Mold Road. Turn left by the traffic lights in abermorddu.
