About Bryniau Gleision
Rising above the western shores of Talybont Reservoir, this quiet Tump offers a tranquil alternative to the crowded peaks of the central Beacons. The terrain is largely grassy and undulating, forming a broad ridge that provides excellent perspectives of the steep-sided Glyn Collwn and the massive eastern slopes of Fan y Big.

- •The name translates from Welsh as 'Blue Hills.' The word 'glas' (plural 'gleision') describes a spectrum of colour including blue, green, and grey; in a landscape context, it often refers to the verdant or hazy quality of the Welsh uplands.
- •From its 538m summit, walkers gain a distinctive profile view of the 'Big Four' Beacons peaks, looking directly across the valley of the Caerfanell to the sharp, diving prow of Fan y Big.
- •The hill is a key component of the 'Talybont Seven'—a challenging 20-mile circuit of the peaks surrounding the Talybont Reservoir, though it is frequently skipped by those taking shorter routes to the higher ground of Waun Rydd.
- •While the name promises 'blue hills,' a visitor’s palette is more likely to consist of various shades of bog-brown and sheep-chewed green, particularly during a standard Welsh downpour.
