This walk visits the fascinating remains of the Glasdir Copper Mines, hidden in a peaceful rural setting at the southern edge of Coed y Brenin. The site was initially worked as opencast in the 1850s but later on underground workings were opened too. There are now well-waymarked walking trails through the area with information boards describing the old buildings and workings. You can also download an audio trail and listen to the history of the mine at the weblink below.
From the starting point near Llanelltyd our route follows the Afon Mawddach upstream, initially on paths and then along a quiet road, before taking a footpath up to the mine. After walking through the old mine workings we head further uphill to join the Precipice Walk high above the steep sides of Foel Cynwch. From here, weather permitting, we hope to experience wonderful views of the Mawddach Estuary. Reaching the shores of Llyn Cynwch, we turn off the main path to head down on a permissive path through fields, continuing back to the start on a quiet lane.
