Clipyn Du [Tarren Bwlch-gwyn] [Siambr Trawsfynydd]

Rising above the remote moorlands north of Pumlumon, this rugged summit is defined by the gritstone escarpment of Tarren Bwlch-Gwyn. It offers a wild, quiet experience overlooking the dark waters of Glaslyn. The terrain is often pathless and peat-heavy, rewarding those who enjoy navigating the emptier, atmospheric corners of Mid Wales.

• •The name Clipyn Du translates from Welsh as 'Black Terrace' or 'Black Little Crag', a likely reference to the dark, shadowed rocks of the escarpment that drops away from the summit plateau.
• •A natural rock cleft on the hill known as Siambr Trawsfynydd is historically significant; Owain Glyndŵr is reputed to have camped his forces here in 1401 prior to his victory at the nearby Battle of Mynydd Hyddgen.
• •The summit offers a commanding perspective of the Pumlumon range to the south, while clear days reveal the sharp profile of Cadair Idris and the Aran mountains to the north.
• •The mountain overlooks the silent, remote waters of Glaslyn, a glacial lake sitting in a dramatic cwm beneath the hill's eastern crags.
• •Due to the lack of established trails and the saturation of the moorland, the local 'path' is often more of a conceptual suggestion than a physical reality.
