Brecon Beacons: Where the SAS Does Its Training, the Waterfalls Are Spectacular, and Someone Just Changed the Name to Bannau Brycheiniog
BRECON — The Brecon Beacons National Park, the highest land in southern Britain and training ground of choice for the SAS, the Royal Marines, and everyone who has ever thought that a sponsored walk sounded straightforward, made headlines in 2023 by officially renaming itself Bannau Brycheiniog — which is the Welsh name and, by general agreement, sounds considerably more dramatic. The landscape did not change. The marketing budget did.
Brecon Beacons / Bannau Brycheiniog
- The SAS Selection Course uses the Brecon Beacons because the conditions can kill you, which the SAS regards as a useful filtering mechanism. The same mountains are simultaneously listed in family walking guides as “ideal for an introductory hill day.” Both descriptions are correct. The trick is knowing which day it is, which the SAS know and the family with the picnic hamper, regrettably, do not.
- Pen y Fan is the highest mountain in southern Britain at 886 metres. It receives approximately 600,000 walkers per year. Despite this, if you ask 100 people in London where Pen y Fan is, 97 will guess Yorkshire, 2 will guess Spain, and one will guess it’s a noodle shop. Wales has perfected the art of containing magnificent things that England has somehow failed to register.
- The renaming from Brecon Beacons to Bannau Brycheiniog in 2023 cost money in stationery, generated newspaper columns of enraged English commentary, and changed precisely nothing about the mountains themselves. The mountains have been the mountains for 400 million years. They will be the mountains long after Twitter is a half-remembered embarrassment. They are calmly indifferent to all of this and quite right too.
- Sgwd yr Eira is a waterfall in the Vale of Neath where the path passes behind the actual curtain of falling water. You can stand in a cave behind a waterfall, with the water roaring past your face, completely free of charge. This is one of the most extraordinary natural experiences in Britain and approximately 4% of England has heard of it. The Welsh are not advertising. The Welsh have figured out something the rest of us haven’t.
- Dan yr Ogof is the longest cave system in western Europe and is co-located with a dinosaur park. Why? Nobody knows. The dinosaurs are not in the caves. The caves are not in the Cretaceous. There are simply life-size dinosaurs at the entrance to a cave system, because somebody in 1981 thought “yes, this will work” and to be fair to them, it has been working ever since. Wales contains multitudes.
Pen y Fan: Britain’s Most Popular Mountain Nobody From Outside Wales Has Heard Of
Pen y Fan, at 886 metres the highest peak in southern Britain, receives approximately 600,000 visitors per year — a figure comparable to Snowdon — and yet exists in a curious cultural semi-obscurity outside Wales. It is steep, spectacular, and straightforward to access via the Storey Arms car park on the A470, which makes it a natural magnet for the sponsored charity walker, the military fitness devotee, and the person who has been told it’s “just a hill” by someone whose relationship with vertical distance is clearly different from their own.
The path to the summit is heavily eroded — a consequence of half a million pairs of boots per year on sandstone that was not designed to function as a motorway — and the Bannau Brycheiniog National Park Authority has invested significantly in path restoration. The work, carried out by conservation volunteers and contractors, involves importing stone by helicopter to the most remote sections, which is a metaphor for the logistical complexity of maintaining open landscapes that people love enough to damage.
Romesh Ranganathan has suggested that “Pen y Fan is the mountain that Wales keeps for itself, which is why every time you go, you’re slightly surprised nobody else seems to know about it.”
The SAS Selection Route: The Beacons After Dark, In a Hurry, In the Wrong Weather
22 SAS, headquartered at Stirling Lines in Hereford, conducts its selection process partially on the Brecon Beacons — specifically the endurance tests that require candidates to carry heavy bergens over multiple mountain routes against demanding time limits, in conditions that the Beacons provide with particular generosity. The Beacons weather — which can shift from mild to seriously hazardous with the speed of a bureaucratic disaster — is, from the SAS perspective, a feature rather than a bug.
Several deaths of selection candidates over the decades have led to reviews of selection procedures and, on occasion, questions in Parliament about the adequacy of risk management for military training in extreme conditions. The landscape itself is indifferent to these discussions and continues to produce the conditions it has always produced. The SAS continues to select in the Beacons. The mountain does not hold a grudge, but it does not soften its conditions for anyone’s feelings about the matter either.
The army’s use of national park land for training is a long-established arrangement that creates occasional tensions with conservation objectives — particularly in areas designated as Sites of Special Scientific Interest — but produces no recorded complaint from the mountain itself, which remains stoic about boots.
The Waterfalls Country: Somewhere Near Pontneddfechan
The southern edge of the Brecon Beacons — specifically the area around the Vale of Neath, Pontneddfechan, and Ystradfellte — contains what is marketed, entirely accurately, as Wales’s Waterfall Country: a concentration of dramatic cascades where the rivers Mellte, Hepste, and Nedd Fechan tumble over old red sandstone and carboniferous limestone in a sequence of falls and gorges that could generate significant tourism revenue if Wales were better at telling people about them.
Sgwd yr Eira on the Hepste is perhaps the finest: a waterfall where the path passes directly behind the curtain of water, allowing walkers to stand behind a full-flow waterfall in a cave formed by the receding rock — one of the most genuinely spectacular walking experiences in Wales and entirely free of charge. The market in spectacular waterfall experiences would price this rather differently were it under different management, a thought that can be held in two ways simultaneously.
Dan yr Ogof: The Cave System Wales Is Quietly Proud Of
Dan yr Ogof, the National Showcase Caves of Wales near Abercraf, contains the longest cave system in western Europe — 17 kilometres of surveyed passages, of which a section is open to visitors. The caves contain spectacular formations, a palaeontological record of Bronze Age burials, and a dinosaur park that was clearly conceived in a moment of commercial inspiration and has remained for reasons that defy simple analysis.
The cave system is a geological consequence of the carboniferous limestone that underlies much of the southern Beacons — the same geology that produces the karst landscape at the surface, with swallowholes, dry valleys, and resurgences that give Waterfall Country its distinctive character. It is also the reason that several rivers in the area disappear underground and reappear elsewhere, which is one of geology’s more entertaining party tricks.
The Name Change: Bannau Brycheiniog and the Welsh Language Reclamation
The renaming of the Brecon Beacons to Bannau Brycheiniog in 2023 by the national park authority was a statement of Welsh linguistic and cultural identity — placing the Welsh name primary while retaining the English name in secondary usage. The authority noted that the original Welsh name was the authentic one, and that the English usage had simply been imposed historically.
The response in the English press oscillated between supportive, bemused, and irritated — a distribution that reflects attitudes to Welsh devolution fairly accurately in miniature. The mountains themselves, which were known by their Welsh names for considerably longer than they were known by English ones, did not appear to take sides.
Bannau Brycheiniog (Brecon Beacons) National Park covers 1,351 square kilometres in south Wales, designated in 1957 and renamed from Brecon Beacons to Bannau Brycheiniog by the national park authority in 2023. The park encompasses four mountain ranges: the Black Mountain (Mynydd Du) in the west, the Fforest Fawr geopark, the Brecon Beacons (Bannau Brycheiniog) range, and the Black Mountains in the east. Pen y Fan (886m) is the highest peak in southern Britain. The park includes Waterfall Country (Vale of Neath), Dan yr Ogof caves, and significant areas used for military training. It attracts approximately 3 to 4 million visitors annually and is within 2 hours of over 7 million people.
