The story that haunts this land
Your journey begins at the National Park Visitor Centre in Libanus, opened in 1971. This main entry point for hikes to Pen y Fan, located near the A470, immerses you in the geology, wildlife, and prehistoric history of the Bannau Brycheiniog National Park. It's here that the foundations of your exploration of the central Wales mountains' monuments are laid, with detailed exhibitions on the Neolithic cairns that dot the region, testifying to human presence thousands of years ago. A first immersion in the heritage of brecon-beacons.
Just 1 km from the Visitor Centre, you reach the Storey Arms Outdoor Centre. This former inn, built between 1840 and 1850 as a coaching inn on the Brecon-Abergavenny road, was transformed in 1951 into an outdoor training center by the British Army for the SAS Fan Dance Test. Located at an altitude of 400m, it's the historic base for ascents of Pen y Fan, the highest peak in South Wales at 886m. This brecon-beacons site, designated a Site of Special Scientific Interest, connects you to the challenges of soldiers and the legends of the mountains.
Continuing the ascent towards Pen y Fan, you encounter Tommy Jones' Obelisk, erected in 1875. This 3m high monument, made of local stone, commemorates Tommy Jones, a 5-year-old child who disappeared in 1873 and was found after 13 days on Fan y Bwlch. It's an emblematic point on the normal route to Pen y Fan, the heart of the Bannau Brycheiniog National Park which attracts 4 million annual visitors. This place of memory and contemplation is a poignant stop on your brecon-beacons scavenger hunt, recalling human fragility in the face of wild nature.
Your thematic circuit then leads you to the Maen Llia Standing Stone, a Neolithic megalith 3.7m high and 1.7m wide, weighing an estimated 10 tons, dated from 4000-2500 BC. Located 4 km west of the Visitor Centre in the Tawe Valley, this menhir is one of the largest in South Wales and is potentially astronomically aligned, linked to prehistoric burial sites. Then, you discover the Sgwd-yr-Eira Waterfall, a 20m cascade on the Hepste River, accessible via a 3 km trail from Pontneddfechan, popular for its hikes in the 'Waterfalls of the Brecon Beacons'.
Finally, your exploration of the central Wales mountains' monuments concludes at Llyn y Fan Fach, a glacial lake at 450m altitude, formed 10,000 years ago. This Site of Special Scientific Interest is surrounded by limestone cliffs in the Black Mountain and is the birthplace of the legend of the Ladies of the Lake, linked to the 13th-century Physicians of Myddfai. Leaving the Brecon Beacons, you take with you not only precise historical facts, but also the echo of myths and the wild beauty of this central Wales mountains heritage, a truly interactive brecon-beacons visit.
