Bwlch y Ddwyallt is the name commonly applied to the high point of the plateau of Gwaun Cerrig Llwydion in the eastern part of the Brecon Beacons in south Wales. It is a top of Waun Rydd.[1]
The plateau reaches its highest point of 754m above sea level on its northern rim overlooking the head of Cwm Cwareli. The name is an odd one to apply to a peak since the Welsh word 'bwlch' generally signifies a col or pass between mountains.[2]
