Bridge in the Llanberis pass.
Llyn Peris, this is a part of the Dinorwig hydroelectric power station. Water from the lake on the top of the mountain drives the turbines and then flows into this lake. At night when the demand for power is low, the turbines become pumps and the water is pumped back up to the top of the mountain.
Still frosty as the sun hasn't made it round as yet. This is the last flat part before I continue the 2 mile climb up the mountain.
