Walk with us and discover the fascinating geological history of Coed y Brenin. Our route follows a combination of forest tracks, minor roads and footpaths, both through the forest and over more open ground. Along the way, we pass several information panels exploring the area’s violent volcanic history, and we visit a number of interesting features. These include the “copper bog” where the peat is so rich in copper that at one time it was dug up and burnt, and the ash residue used as a source of copper. A slight detour from the main path takes us to a delightful waterfall into a pretty pool. With parts of the forest now felled, we will be able to enjoy amazing views down the valley from the higher reaches of the route, weather permitting, of course.
