Bannau Brycheiniog (the Brecon Beacons) is a mountain range in South Wales. In a narrow sense, the name refers to the range of Old Red Sandstone peaks popular with walkers which lie to the south of Brecon. Sometimes referred to as "the central Beacons" they include South Wales' highest mountain, Pen y Fan. The range forms the central section of the Brecon Beacons National Park (Parc Cenedlaethol Bannau Brycheiniog), a designation which also encompasses ranges both to the east and the west of "the central Beacons". This much wider area is also commonly referred to as "the Brecon Beacons".
Starting at car park south of Craig y fan ddu we headed north up and round to waun rydd. We then headed west along the ridge towards pen y fan and down to the lake NW of it. There we wild camped and went out to do night nav. Up to corn Du in the morning, headed south and down to the south of Neuadd reservoir along the foot paths and back to the car. The weather was very windy, I was being blown about and it was fine near the bottom but at about 670m there was frost on the ground and we were in the clouds
