Bwlch y Ddwyallt [Gwaun Cerrig Llwydion]

Marking the dramatic junction where the ridges of Craig y Fan Ddu and the main Beacons spine meet, this high plateau offers a wilder feel than its famous neighbours. While the summit is a broad, peaty expanse, its eastern edge drops sharply away, providing commanding views down the length of the Talybont Valley.

• •The name Bwlch y Ddwyallt translates from Welsh as 'Pass of the Two Wooded Slopes', though the summit plateau itself is more commonly known to locals as Gwaun Cerrig Llwydion, meaning 'Moor of the Grey Stones'.
• •Standing as the highest point on the rim of the Talybont Valley, the summit offers a spectacular perspective of the Talybont Reservoir and a clear line of sight across to the Black Mountains on the eastern horizon.
• •This hill serves as a vital link in the classic Central Beacons circuit; it connects the dramatic escarpment of Craig y Fan Ddu to the peaks of Fan y Big and Cribyn, forming the eastern arm of the Taf Fechan horseshoe.
• •The terrain is characterized by extensive peat hags and deep gullies, which can make crossing the plateau a slow, tactical exercise in navigation when the mist descends over the flat ground.
• •It is a summit where the most interesting features are found at the edges; the actual high point is so subtle that many walkers only realize they have reached it when they notice the ground finally beginning to tilt toward Pen y Fan.
