Craig Cerrig-gleisiad

Craig Cerrig-gleisiad is a mountain summit in Brecon Beacons National Park, Wales, rising to 629 meters above sea level. The north-facing side features steep cliffs while a distinctive L-shaped glacial cwm opens toward the northeast, shaping the terrain.

The summit's current shape was carved by glacial processes during the last ice age when thick ice sheets shaped the landscape. A significant portion of the west wall collapsed after the ice retreated.

The name comes from Welsh and means 'rocky blue hill', reflecting the natural characteristics of this geological formation in South Wales. Visitors can walk through the landscape and encounter traditional Welsh place-naming that describes the land itself.

Several hiking trails lead to the summit with parking available nearby. Keep dogs on a leash throughout your visit since livestock graze in the area.

The cliffs serve as nesting sites for peregrine falcons, which are impressive hunters of the sky. The area also hosts rare Arctic-alpine plants not commonly seen this far south in Britain.
