Aerial view of the bridges between the two shores of the twin lakes of LLyn Padarn and Llyn Peris. Plain to see also is the buildings and yard of what was the Dinorwic Slate Quarry, but which now houses the National Slate Museum of Wales. Towards the top of the image can be seen the start of the entrance to the Electric Mountain which is the Dinorwic Power Station inside the Elidir Fawr mountain.
