Why it's Wildland
6.4At the head of the Elan Valley, Craig Goch pairs a high, curved masonry dam with open reservoir water and a view down the valley. It is both a striking piece of Victorian water engineering and a starting point for a longer walk through the reservoir landscape.
The appeal here is the meeting of landscape and infrastructure: a substantial dam at the upper end of a Welsh reservoir valley, with water on one side and a long view down the valley on the other. For more than a quick look, the Elan Valley Trail makes the dam a destination on a proper landscape walk.
