I second that!I know Dinorwig is probably overlooked due to the amount of people who have visited the place,but for me it still has a very special atmosphere there.Many times I walked from the museum car park,up the C inclines,then up the foxes path to Garret,Australia,Braich and Lernion galleries.If nothing else you get a sense of the difficult conditions people worked in(and how much of a job it was just getting to work).There is a strange sense of quiet in this vast derelict place,what a different place it must have been when working.Nice to see and hear the train going up Snowdon in the distance!
It is also surprising how the weather can change these sorts of landscapes for the purposes of photography.
