Brecon Beacons National Park, officially National Park (), is a national park in Wales. It is named after the Brecon Beacons, or in Welsh, the mountain range at its centre. This range includes the highest mountain in South Wales, , which has an elevation of .
The national park has a total area of . The Brecon Beacons and uplands form the central section of the park. To the east are the Black Mountains, which extend beyond the national park boundary into England, and to the west is the similarly named but distinct Black Mountain range. These ranges share much of the same basic geology, the southerly dip of the rock strata leading to north-facing escarpments. The highest peak of the Black Mountains is (), and () is the highest of the Black Mountain.
The park was founded in 1957 and is the third and most recently designated national park in Wales, after Snowdonia () and the Pembrokeshire Coast. It is visited by approximately 4.4 million people each year.
Toponymy The name is first attested in the sixteenth century, and "Brecon Beacons" first occurs in the eighteenth century as "Brecknock Beacons". derives from the Welsh , , and , the name of an early medieval kingdom which covered the area. The English name is derived from the Welsh one; in the eleventh century the town of Brecon is recorded as "Brecheniauc", which became "Brecknock" and "Brecon".
In a paragraph on Brecknockshire, John Leland's 1536–1539 Itinerary treats the ranges between Monmouth and Carmarthen as a single mountain named "Black Mountain". He goes on to ascribe the name "Banne Brekeniauc" to the hills surrounding "Artures Hille" (Pen-y-Fan), also calling the range the "Banne Hilles".
The term "Brecknock Beacons" was used in the eighteenth century and referred to the area around Pen y Fan, which was itself was sometimes called "the (Brecknock) Beacon". For instance, Emanuel Bowen's 1729 New and accurate map of South Wales labels the peak as "The Vann or Brecknock Beacon", John Clark's 1794 General View of the Agriculture of the County of Brecknock refers to "the Vann, or Brecknock Beacon, the undisputed sovereign of all the mountains in South Wales", and an 1839 tithe map of Cantref parish labels the mountain simply "Beacon". A slightly wider definition was used in 1809 by the Breconshire historian Theophilus Jones, who wrote that "of the lofty summits of the Brecknock Beacons, that most southwards is the lowest, and the other two nearly of a height, they are sometimes called Cader Arthur or Arthur's chair".
To distinguish the Brecons Beacons range from the national park, the range is sometimes called the "Central Beacons". In April 2023, the national park changed its name to "" in English, abandoning the previous English name Brecon Beacons.
Geography
The area covered by the national park stretches from Llandeilo in the west to Hay-on-Wye in the northeast and Pontypool in the southeast, covering . It principally consists of three mountain ranges; the Black Mountains in the east, the Brecon Beacons and Fforest Fawr uplands in the centre, and the Black Mountain in the west. The park is entirely within Wales and therefore excludes the Olchon Valley and Black Hill, which are part of the Black Mountains but in the English county of Herefordshire.
The central Brecon Beacons range comprises six main peaks, which from west to east are: Corn Du, ; Pen y Fan, the highest peak, ; Cribyn, ; Fan y Bîg, ; Bwlch y Ddwyallt, ; and Waun Rydd, . These summits form a long ridge, and the sections joining the first four form a horseshoe shape around the head of the Taf Fechan, which flows away to the southeast. To the northeast of the ridge, interspersed with long parallel spurs, are four cirques (Welsh: cwm) or four round-headed valleys, which from west to east these are Cwm Sere, Cwm Cynwyn, Cwm Oergwm and Cwm Cwareli.
The Black Mountains in the east are clearly separated from the central Beacons range by the Usk valley between Brecon and Abergavenny. Waun Fach () is the highest mountain in this range.
The Brecon Beacons range, Fforest Fawr, and Black Mountain form a continuous massif of high ground above . The A470 road forms the approximate boundary between the central Beacons and Fforest Fawr. The highest peak of the Black Mountain is Fan Brycheiniog, at . There are notable waterfalls in this area, including the Henrhyd Falls and the Ystradfellte falls to the south of Fforest Fawr. The Ogof Ffynnon Ddu cave system is on the southwestern edge of Fforest Fawr.
Numerous town and community councils operate within these areas and include the town councils for Brecon and Hay on Wye and the community councils for Cefn-coed-y-cymmer, Llanfihangel Cwmdu with Bwlch and Cathedine, Llangattock, Llangors, Llanthony, Llywel, Pontsticill, Pontsarn and Vaynor, Talybont-on-Usk, Trallong, Trecastle and Ystradfellte.
Geology
The geology of the national park consists of a thick succession of sedimentary rocks laid down from the late Ordovician through the Silurian and Devonian to the late Carboniferous period. The rock sequence most closely associated with the park is the Old Red Sandstone from which most of its mountains are formed. The older parts of the succession, in the northwest, were folded and faulted during the Caledonian orogeny. Further faulting and folding, particularly in the south of the park is associated with the Variscan orogeny.
History The area was inhabited during the Neolithic and the succeeding Bronze Age, the most obvious legacy of the latter being the numerous burial cairns which adorn the hills of the centre and west of the National Park. There are remnants of round barrows on Fan Brycheiniog, Pen y Fan and Corn Du. The former was excavated in 2002–4 and the ashes in the central cist dated to about 2000 BCE using radiocarbon dating. A wreath of meadowsweet was probably placed in the burial.Hughes, Gwilym and Murphy, Ken, Fan Foel round barrow, Mynydd Du, South Wales: archaeological excavation and palaeoenvironmentalanalysis 2002-04, Journal of the Cambrian Archaeological Association, Volume 162, 2013.

Over twenty hillforts were established in the area during the Iron Age. The largest, and indeed the largest in South Wales, were the pair of forts atop y Garn Goch near Bethlehem, Carmarthenshire – y Gaer Fawr and y Gaer Fach – literally "the big fort" and "the little fort". The forts are thought to have once been trading and political centres.
When the Romans came to Wales in 43 CE, they stationed more than 600 soldiers in the area. Y Gaer, near the town of Brecon was their main base. During the Norman Conquest many castles were erected throughout the park, including Carreg Cennen Castle. Brecon Castle is of Norman origin.
There are many old tracks which were used over the centuries by drovers to take their cattle and geese to market in England. The drovers brought back gorse seed, which they sowed to provide food for their sheep.
The area played a significant role during the Industrial Revolution as various raw materials including limestone, silica sand and ironstone were quarried for transport southwards to the furnaces of the industrialising South Wales Valleys.
The Brecon Beacons Mountain Centre was opened in 1966 to help visitors understand and enjoy the area. This western half of the national park gained European and global status in 2005 as Fforest Fawr Geopark, which includes the Black Mountain, the historic extent of Fforest Fawr, and much of the Brecon Beacons range and surrounding lowlands.Welcome – Brecon Beacons National Park, Wales .

In 2006 and 2007, controversy surrounded the government decision to build the South Wales Gas Pipeline through the park, the National Park Authority calling the decision a "huge blow".Controversial National Grid Pipeline given the go ahead! Brecon Beacons National Park Authority
Natural history Most of the national park is bare, grassy moorland grazed by Welsh mountain ponies and Welsh mountain sheep, with scattered forestry plantations, and pasture in the valleys. Common ravens, red kites, peregrine falcons, northern wheatears, ring ouzels, and the rare merlin breeds in the park.
National park
The Brecon Beacons National Park was established in 1957, the third of the three Welsh parks after Snowdonia in 1951 and the Pembrokeshire Coast National Park in 1952. It covers an area of , which is much larger than the Brecon Beacons range. Over half of the park is in the south of Powys; the remainder of the park is split between northwestern Monmouthshire, eastern Carmarthenshire, northern Rhondda Cynon Taf and Merthyr Tydfil, and very small areas of Blaenau Gwent, and Torfaen.
The Park as designated in 1957 covered a slightly smaller area than it does presently. A 'Variation Order' was made in June 1966 to extend it by about at its southeastern extremity. West of the canal, the boundary had previously been drawn along the boundary between the (then) administrative parishes of Llanover and Goytre.Brecon Beacons National Park Designation (Variation) Order 1966 made by Secretary of State, The Welsh Office, Cathays Park, Cardiff
The park is managed by Bannau Brycheiniog National Park Authority, a special purpose local authority with responsibilities to conserve and enhance the natural beauty of the park, aid visitors' enjoyment of the park, and support the economic and social well-being of local communities. The National Park Authority has 18 members, twelve are appointed by the area's local authorities and six by the Welsh Government. Of the local authority members six are appointed by Powys County Council, and one each by the councils of Blaenau Gwent, Carmarthenshire, Merthyr Tydfil, Monmouthshire, Rhondda Cynon Taf, and Torfaen. There is also a standards committee with three members. Between 1995 and 2020 the park authority had 24 members, sixteen appointed by the local authorities and eight by the government.
Activities Outdoor activities in Brecon Beacons National Park include walking, cycling, mountain biking and horse riding, as well as sailing, windsurfing, canoeing, fishing, rock climbing, hang-gliding, caravanning, camping and caving. A long-distance cycling route, the Taff Trail, passes over the Beacons on its way from Brecon to Cardiff, and in 2005 the first walk to span the entire length of the park was opened. The route, called the Beacons Way, runs from Abergavenny via The Skirrid () in the east and ends in the village of Llangadog in Carmarthenshire in the west.
Brecon Mountain Railway A railway with narrow gauge trains is run by the Brecon Mountain Railway. The railway is a narrow gauge tourist railway on the south side of the Brecon Beacons. It climbs northwards from Pant along the full length of the Pontsticill Reservoir (also called 'Taf Fechan' reservoir by Welsh Water) and continues past the adjoining Pentwyn Reservoir to Torpantau railway station. The railway's starting point at Pant is located north of Merthyr Tydfil town centre.
Mountain rescue
Mountain rescue in south Wales is provided by five volunteer groups, with the police having overall command. In serious situations they were historically aided by Royal Navy or Royal Air Force helicopters from RM Chivenor or RAF Valley, but since 2015 this task has been performed by Bristow Helicopters on behalf of HM Coastguard. The five groups are:
