Excellent sight looking across Llyn Peris which is 503mtrs above sea level. Dinorwig hydroelectric power station is straight across the lake, this generates 1728MW of power. There are 16 kilometres of deep tunnels in Elidir Mountain. This was opened in 1984

This elevated point had excellent views looking down on Llyn Peris lake and around the old slate quarry. The wild goats were basking in the sun less than 100 metres away. You can get quite close to the goats, but too close and they move away slightly.
