Brecon Beacons National Park, also known as Bannau Brycheiniog National Park in Welsh, is a national park located in Wales. It is named after the Brecon Beacons, or Bannau Brycheiniog in Welsh, which is the mountain range at the center of the park. The national park includes Pen y Fan, the highest mountain in South Wales, which is 886 meters (2,907 feet) high.
The park covers an area of 1,344 square kilometers (519 square miles). The central part of the park includes the Brecon Beacons and Fforest Fawr uplands. To the east of the park are the Black Mountains, which extend beyond the park's boundary into England. To the west is the Black Mountain range, which has a similar name but is a different area. These mountain ranges share similar geological features, with rock layers sloping downward to the south, creating steep slopes that face north. The highest peak in the Black Mountains is Waun Fach, which is 811 meters (2,661 feet) high. The highest peak in the Black Mountain is Fan Brycheiniog, which is 802.5 meters (2,633 feet) high.
The park was established in 1957 and is the third national park in Wales, following Snowdonia (Eryri) and the Pembrokeshire Coast. Each year, about 4.4 million people visit the park.
Toponymy
The name Bannau Brycheiniog was first recorded in the 1500s, and "Brecon Beacons" first appeared in the 1700s as "Brecknock Beacons." The name Bannau Brycheiniog comes from the Welsh words bannau, meaning "peaks," and Brycheiniog, the name of an early medieval kingdom that covered the area. The English name is based on the Welsh one. In the 1000s, the town of Brecon was written as "Brecheniauc," which later became "Brecknock" and "Brecon."
In a paragraph about Brecknockshire, John Leland's 1536–1539 Itinerary described the mountain ranges between Monmouth and Carmarthen as one large mountain called "Black Mountain." He also named the hills around "Artures Hille" (Pen-y-Fan) "Banne Brekeniauc" and referred to the range as "Banne Hilles."
The term "Brecknock Beacons" was used in the 1700s to describe the area around Pen y Fan, which was sometimes called "the (Brecknock) Beacon." For example, Emanuel Bowen's 1729 map of South Wales labeled the peak "The Vann or Brecknock Beacon." John Clark's 1794 book about Brecknockshire called the mountain "the Vann, or Brecknock Beacon, the highest and most important mountain in South Wales." An 1839 map of Cantref parish simply marked the mountain as "Beacon." In 1809, the Breconshire historian Theophilus Jones described the three tall peaks of the Brecknock Beacons, noting that the southernmost peak was the lowest, while the other two were nearly the same height. He sometimes called them "Cader Arthur" or "Arthur's Chair."
To differentiate the Brecon Beacons range from the national park, the range is sometimes called the "Central Beacons." In April 2023, the national park changed its English name to "Bannau Brycheiniog," replacing the previous name "Brecon Beacons."
Geography
The national park covers an area from Llandeilo in the west to Hay-on-Wye in the northeast and Pontypool in the southeast, spanning 519 square miles (1,340 square kilometers). It mainly includes three mountain ranges: the Black Mountains in the east, the Brecon Beacons and Fforest Fawr uplands in the center, and the Black Mountain in the west. The park is entirely within Wales, so it does not include the Olchon Valley and Black Hill, which are part of the Black Mountains but located in the English county of Herefordshire.
The central Brecon Beacons range includes six main peaks, listed from west to east as: Corn Du (873 meters or 2,864 feet), Pen y Fan (the highest peak at 886 meters or 2,907 feet), Cribyn (795 meters or 2,608 feet), Fan y Bîg (719 meters or 2,359 feet), Bwlch y Ddwyallt (754 meters or 2,474 feet), and Waun Rydd (769 meters or 2,523 feet). These peaks form a long ridge, and the sections connecting the first four create a horseshoe shape around the head of the Taf Fechan, which flows southeast. To the northeast of the ridge, four cirques (Welsh: cwm) or round-headed valleys are found. These, from west to east, are Cwm Sere, Cwm Cynwyn, Cwm Oergwm, and Cwm Cwareli.
The Black Mountains in the east are separated from the central Beacons range by the Usk valley between Brecon and Abergavenny. Waun Fach (811 meters or 2,661 feet) is the highest mountain in this range.
The Brecon Beacons range, Fforest Fawr, and Black Mountain together form a continuous area of high ground above 300 meters (980 feet). The A470 road roughly marks the boundary between the central Beacons and Fforest Fawr. The highest peak in the Black Mountain is Fan Brycheiniog, at 802.5 meters (2,633 feet). Notable waterfalls in this area include Henrhyd Falls, which is 90 feet (27 meters) tall, and Ystradfellte Falls to the south of Fforest Fawr. The Ogof Ffynnon Ddu cave system is located on the southwestern edge of Fforest Fawr.
Many town and community councils operate within the park. These include the town councils for Brecon and Hay on Wye, and 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.
The geology of the national park includes thick layers of sedimentary rocks formed from the late Ordovician period through the Silurian, Devonian, and late Carboniferous periods. The rock sequence most closely linked to the park is the Old Red Sandstone, from which many of its mountains are formed. The older parts of the rock layers in the northwest were folded and faulted during the Caledonian orogeny. Additional faulting and folding, especially in the southern part of the park, occurred during the Variscan orogeny.
History
The area was home to people during the Neolithic period and the Bronze Age that followed. One clear sign of the Bronze Age is the many burial cairns, or stone mounds, found on the hills in the center and west of the National Park. Remnants of round barrows, which are types of ancient burial mounds, can be seen on Fan Brycheiniog, Pen y Fan, and Corn Du. The site on Fan Brycheiniog was studied from 2002 to 2004, and the remains inside a central stone box were dated to about 2000 BCE using a scientific method called radiocarbon dating. A wreath made of meadowsweet flowers was likely placed in the burial.
Over twenty hillforts were built in the area during the Iron Age. The largest of these, and the largest in South Wales, were two forts on y Garn Goch near Bethlehem, Carmarthenshire: y Gaer Fawr and y Gaer Fach, which mean "the big fort" and "the little fort." These forts are believed to have been important places for trade and leadership.
When the Romans arrived in 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 built in the park, including Carreg Cennen Castle. Brecon Castle was built by the Normans.
Old paths used by drovers, or farmers who moved animals, were used for centuries to take cattle and geese to markets in England. These drovers brought back gorse seeds, which they planted to feed their sheep.
The area was important during the Industrial Revolution because materials like limestone, silica sand, and ironstone were mined and sent south to the industrial areas of South Wales.
The Brecon Beacons Mountain Centre opened in 1966 to help visitors learn about the area. In 2005, the western part of the national park was named Fforest Fawr Geopark, which includes the Black Mountain, parts of the Brecon Beacons, and surrounding lowlands. The entire park became an International Dark Sky Reserve in 2013.
In 2006 and 2007, there was controversy over a government plan to build the South Wales Gas Pipeline through the park. The National Park Authority called the decision a "huge blow."
Most of the park is open, grassy moorland where Welsh mountain ponies and sheep graze. There are also small areas of forests and fields in the valleys. Birds such as common ravens, red kites, peregrine falcons, northern wheatears, ring ouzels, and the rare merlin live in the park.
The Brecon Beacons National Park was created in 1957, making it the third of the three Welsh national parks after Snowdonia (1951) and the Pembrokeshire Coast (1952). It covers about 519 square miles (1,340 km²), which is much larger than the Brecon Beacons mountain range itself. More than half of the park is in the south of Powys, while the rest is divided among parts of Monmouthshire, Carmarthenshire, Rhondda Cynon Taf, Merthyr Tydfil, and small areas of Blaenau Gwent and Torfaen.
The park's original boundaries in 1957 were slightly smaller than they are today. In 1966, a "Variation Order" expanded the park by about 4.5 square miles (12 km²) at its southeastern edge. Before this change, the boundary near the canal followed the edges of the (then) administrative areas of Llanover and Goytre.
The park is managed by Bannau Brycheiniog National Park Authority, a group responsible for protecting the park's natural beauty, helping visitors enjoy it, and supporting local communities. The authority has 18 members: twelve are chosen by local governments, and six by the Welsh Government. Six of the local members are selected by Powys County Council, and one each by councils in Blaenau Gwent, Carmarthenshire, Merthyr Tydfil, Monmouthshire, Rhondda Cynon Taf, and Torfaen. There is also a standards committee with three members. From 1995 to 2020, the authority had 24 members: sixteen from local governments and eight from the government.
Activities
Outdoor activities in Brecon Beacons National Park include walking, cycling, mountain biking, horse riding, sailing, windsurfing, canoeing, fishing, rock climbing, hang-gliding, caravanning, camping, and caving. A long-distance cycling route called the Taff Trail passes through the Brecon Beacons on its way from Brecon to Cardiff. In 2005, the first walking path that goes all the way across the park was opened. The 99-mile (159 km) route, named the Beacons Way, starts in Abergavenny and goes through The Skirrid (Ysgyryd Fawr) in the east. The path ends in the village of Llangadog in Carmarthenshire in the west.
Brecon Mountain Railway
The Brecon Mountain Railway operates a narrow gauge train line. The railway has a track width of 1 foot 11 and 3/4 inches (603 mm) and is located on the southern side of the Brecon Beacons. The route begins at Pant, two miles (3 km) north of Merthyr Tydfil town center. It travels north along the Pontsticill Reservoir, also known as the Taf Fechan Reservoir by Welsh Water, and continues past the nearby Pentwyn Reservoir. The railway ends at Torpantau railway station.
Mountain rescue
Mountain rescue in south Wales is handled by five volunteer groups, with the police in charge of overall operations. In the past, serious situations were helped by Royal Navy or Royal Air Force helicopters from RM Chivenor or RAF Valley. Since 2015, this task has been done by Bristow Helicopters on behalf of HM Coastguard. The five groups are:
- CBMRT – Central Beacons Mountain Rescue Team
- BMRT – Brecon Mountain Rescue Team
- LMRT – Longtown Mountain Rescue Team based in the east
- WBMSART – Western Beacons Mountain Search and Rescue Team
- SARDA South Wales – Search and Rescue Dog Association covering South and Mid Wales
These groups are mainly funded by donations. Their work includes mountain rescue but also helps the police search for missing or vulnerable people in the community.
Military training
The Brecon Beacons are used to train members of the UK armed forces and military reservists. The Army’s Infantry Battle School is located in Brecon, and the Special Air Service (SAS) and Special Boat Service use the area to test how well applicants can handle physical challenges. A unique training exercise in the area is called the "Fan dance," which takes place on Pen y Fan. In July 2013, three soldiers died due to overheating or heatstroke during an SAS selection exercise. Earlier in the same year, an army captain was found dead on Corn Du after training in freezing weather for the SAS.
Use ofBannau Brycheiniogin English
On April 17, 2023, it was announced that the National Park officially changed its name to Bannau Brycheiniog in both Welsh and English. The new English name is now Bannau Brycheiniog National Park, or "the Bannau" for short. The name change took effect on the same day, which marked the 66th anniversary of the park's creation.
The park authority explained that the change aims to highlight the area's culture and heritage. It is also part of a larger plan to improve how the park is managed and to address environmental issues, such as climate change. This includes removing references to beacons that produce carbon emissions. The goal to make the park carbon neutral by 2035 was supported by Welsh actor Michael Sheen. Some people said the change made them proud of the Welsh language, while others said both names might still be used. As part of the change, the park replaced its old logo, which showed a lit beacon, with a new one. Plaid Cymru’s Welsh language representative supported the move, and the Welsh Liberal Democrats welcomed the decision. Conservative MP James Evans said the change was not a priority for locals and raised concerns about costs. Local Conservative MP Fay Jones said the English name could have remained. Prime Minister Rishi Sunak said he would continue to call the park "Brecon Beacons," as would most people.
Catherine Mealing-Jones, the park authority’s CEO, said the name "Brecon Beacons" does not have a clear meaning in Welsh. She added that a large beacon that burns carbon is not a good image for an environmental organization. Mealing-Jones said people can still use either name, but the change is not required. She hoped the focus on the Welsh name would encourage more people to use it. She also said the park has always used "Bannau Brycheiniog" as the Welsh name and wanted to celebrate Welsh culture, food, and farming.
In May 2023, more than 50 local businesses in the park campaigned to restore the name "Brecon Beacons" alongside the Welsh name. They said the decision did not respect Wales as a bilingual country because it did not treat English and Welsh equally. They also said park ambassadors were not asked for their opinions on the name change. A digital marketer said the campaign would not affect tourism, and the park authority said it will focus on Welsh names in the future.
In February 2026, the park authority announced it would standardize the spelling of Welsh-language place names and use them more often than English names on signs, social media, and in written materials.
