A hike up the Elan Valley in mid-Wales, from the bottom to the top.
On the way we'll see the Caban Coch dam, the Garreg Ddu dam, the Pen-y-Garreg dam and finally, at the top, the Craig Goch dam.
I explain the history of the valley, the construction of the dams and then follow the Elan Valley Aqueduct to Birmingham.
