About Carn Hyddgen [Carn Gwilym]
Tucked away in the remote Pumlumon heartland, this grassy, peat-covered dome offers a sense of total isolation. Reached by long approaches from the Nant-y-moch reservoir, the summit plateau is a wild spot steeped in medieval history, overlooking the source of the River Rheidol and the sprawling Cambrian Mountains.
