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".
Started at the car park (SO 024 248). Went up over Pan Y fan then Corn Du and along Craig Gwaun Taf and Craig Fan Ddu. At the 642 trig point I headed East across the dam then south through Taf Fechan forest. Followed the trail onto the Taff Trail and back North up towards Craig y Fan Ddu on the beacons way. Kept going North and at grid SO 057 205 headed south east to Allt Lwyd. From here I went to Twyn Du to the North then headed West to Fan Y Big, Cribyn, Pen Y Fan, Corn Du. Past Obelisk then North Nant Cwm Llwch and back to the carpark.
