About Craig Cerrig-gleisiad

Rising as a dramatic glacial amphitheatre within the Fforest Fawr, this Hewitt offers a quieter alternative to the central peaks. While the summit is a gentle, grassy plateau, the real character lies in the sheer sandstone cliffs of its northern face, which shelter rare arctic-alpine flora and overlook the Tarell Valley.

Did You Know?

  • The Welsh name translates as 'Crag of the Blue Stones,' referring to the shadowed hue of the Old Red Sandstone cliffs. While 'gleisiad' can also mean salmon, the geological interpretation is more likely given the craggy inland terrain.
  • As a designated National Nature Reserve, the hill is home to the southernmost populations of several arctic-alpine plants in Britain, including purple saxifrage, which thrive in the cool, north-facing gullies away from direct sunlight.
  • The summit is often visited as part of a horseshoe loop with Fan Frynych. This route offers a grandstand view of the 'Big Three' central Beacons—Pen y Fan, Corn Du, and Cribyn—from a perspective few tourists ever see.
  • The great northern cwm is a classic glacial cirque, carved during the last Ice Age. Unlike the busier peaks nearby, the steep scree slopes and crags here feel wilder and more prehistoric.
  • Despite its impressive northern face, the actual summit is so stubbornly flat and grassy that reaching the highest point feels less like a mountaineering triumph and more like wandering into a very elevated, very breezy sheep pasture.
