Bannau Brycheiniog: The National Park That Changed Its Name (and Why That Matters)

In April 2023, the Brecon Beacons National Park formally changed its name to Bannau Brycheiniog (pronounced Ban-eye Bruck-ein-iog, meaning “The Peaks of Brychan’s Kingdom”), abandoning the English name that had been in use since the park was established in 1957. The reasoning was simple: the park’s signage, literature, and communications now prioritise Welsh-language place-names; the “Brecon Beacons” name had no evidence of historical beacons on the summits and covered only a small section of the park’s actual geography. By 2026, the transition is largely complete in official communications, though the older English name still gets used informally and appears on older maps and in many travel guides.

This is worth knowing before you arrive and find signs that don’t match what you were expecting. It is also worth understanding as a statement: Wales takes its language seriously in a way that other devolved regions often do not, and the park system has been a part of that recovery.

The park itself covers 520 square miles of South Wales, taking in the central Beacons range (Pen y Fan and Corn Du), the Black Mountains in the east, the Black Mountain (singular) in the west, and the Waterfall Country along the Nedd and Mellte rivers. It is 90 minutes from Cardiff, 2.5 hours from London.

Pen y Fan

Pen y Fan, at 886 metres the highest point in South Wales and in all of England and Wales south of Snowdonia, is the park’s signature climb. The most direct ascent from the Storey Arms car park on the A470 takes about 90 minutes each way. The ridge connecting Pen y Fan to its near-equal neighbour Corn Du (884m), and continuing east to Cribyn and Fan y Big, is the Horseshoe route: 5-7 hours of excellent ridge walking with views extending to the Bristol Channel on clear days.

The Pen y Fan summit is busy on weekends from spring through autumn. A 7am start on a Saturday in June gives you the summit in quiet before the main wave of walkers arrives from 10am onwards. Midweek in October is the ideal combination of autumn colour, manageable crowd levels, and reasonable weather probability.

Weather deteriorates rapidly above 700 metres. The summit has claimed lives from hypothermia in conditions that seemed unremarkable at the carpark. Bring waterproofs, extra layers, and a map even in summer.

Waterfall Country

The area around Pontneddfechan and Ystradfellte has a concentration of waterfalls accessible by woodland paths along the Afon Mellte, Afon Hepste, and Afon Nedd Fechan. The Sgwd yr Eira fall (Fall of Snow) is the most famous: a path runs behind the curtain of water, allowing you to walk through it. The full Waterfall Country circuit covers 10km and takes about 4-5 hours through old-growth oak woodland and limestone gorges. The paths can be slippery; walking poles and proper footwear are practical.

The Dark Skies

Bannau Brycheiniog has International Dark Sky Reserve status, which in practice means that on a clear moonless night in the uplands, the Milky Way is visible as a structural feature of the sky. The Usk Reservoir, the hillside above Llanthony Priory, and the car park at Storey Arms are among the better accessible viewing points. The park authority runs organised stargazing events; check bannaubrycheiniog.org for the schedule.

Where to Stay and Eat

Brecon town (the main service hub) has several guesthouses and hotels. The Hardwick at Abergavenny (at the eastern edge of the park) does excellent modern cooking with local ingredients and a proper wine list; this is where serious visitors eat. For something more casual, the pubs in the villages along the A40 corridor serve reliable food and locally brewed ales.

The park is accessible from Cardiff by train to Abergavenny or Merthyr Tydfil, then by bus into the park interior (services are infrequent). A car gives vastly more flexibility. The A40 from Brecon east to Abergavenny, or west through Llandovery, connects most of the park’s main areas.
