Distinctive Plateau and Summit in the Brecon Beacons
Gwaun Cerrig Llwydion is a prominent upland plateau located in the eastern section of the Brecon Beacons National Park in south Wales. The plateau reaches its highest point at Bwlch y Ddwyallt, standing at 754 meters above sea level. This summit is notable for its expansive views overlooking the head of Cwm Cwareli valley. The name Bwlch y Ddwyallt is somewhat unusual as 'bwlch' typically means a mountain pass, yet here it denotes the peak of the plateau. The terrain is characterized by broad, open moorland and steep edges that provide dramatic vistas across the surrounding landscape.Geological Foundations and Landscape Features
The plateau’s geology is dominated by hard-wearing sandstones from the Devonian period, specifically the Plateau Beds Formation of the Old Red Sandstone. These rock layers lie atop the Brownstones Formation, also Devonian in age, which forms much of the hill’s bulk. Evidence of glaciation during the ice ages is visible in the cliffs below Bwlch y Ddwyallt and nearby Graig Fan Las, adding to the area's geological interest. The rugged sandstone cliffs and moorland create a wild and natural environment that is both visually striking and ecologically significant.Hiking and Outdoor Experience
Gwaun Cerrig Llwydion is classified as open country, allowing free access for walkers and hikers. It forms part of the extensive Brecon Beacons trail network, with the Beacons Way running along its southern edge. Other footpaths encircle the plateau, connecting it to neighboring peaks such as Fan y Big and Cribyn. The terrain offers a mix of broad ridge walking and steep descents, ideal for hikers seeking both challenge and scenic reward. The plateau’s open nature provides a sense of vastness and tranquility, making it a favored spot for nature lovers and outdoor enthusiasts.Natural Environment and Wildlife Habitat
The plateau’s upland moorland supports a variety of wildlife typical of the Brecon Beacons, including upland birds and hardy plant species adapted to the exposed conditions. The landscape’s openness and minimal human development contribute to its status as an important habitat within the national park. Visitors can enjoy the peaceful atmosphere and the opportunity to observe nature in a relatively undisturbed setting.Connection to Local Culture and Geography
Situated near the village of Llanfrynach and the town of Merthyr Tydfil, Gwaun Cerrig Llwydion is part of a culturally rich region of Wales. The area’s Welsh place names reflect its heritage and the longstanding relationship between the land and local communities. The plateau also marks the source area of the River Caerfanell, which flows steeply down from this high ground, adding hydrological significance to the site.Visitor Information and Accessibility
The area is accessible year-round and offers a natural escape for walkers of varying abilities, though some routes require moderate fitness due to elevation and terrain. There are no formal opening hours as it is open countryside, but visitors should prepare for variable weather conditions typical of upland Wales. Nearby visitor centers in the Brecon Beacons provide additional information and support for exploring the region.Iconic landmarks you can’t miss
