Carnedd y Filiast

Standing as the northern bastion of the Glyderau, this 821m Hewitt offers a starkly different character to the jagged peaks further south. Renowned for its immense, smooth Atlantic Slabs, the summit provides an airy perch overlooking the deep glacial trough of Nant Ffrancon and the sprawling slate-quarried slopes above Bethesda.

• •The name translates from Welsh as 'Cairn of the Greyhound Bitch'. In local folklore, a 'miliast' often refers to a legendary female creature or the hunting hounds of medieval princes who used these high ridges as seasonal hunting grounds.
• •The mountain is famous among scramblers for the Atlantic Slabs on its western flanks. These are expansive, tilted sheets of Ordovician volcanic rock that provide long, clean routes for those who prefer a hands-on approach to the summit.
• •It is frequently bagged as the first or last peak of a full Glyderau traverse, connected to its neighbour Y Garn by a broad, high-altitude ridge that stays well above the 700-metre mark.
• •The summit offers one of the best profile views of the Carneddau range, specifically the intimidatingly steep southern face of Pen yr Ole Wen rising directly across the Ogwen Valley.
• •Despite the name suggesting a canine memorial, you are significantly more likely to encounter a stray, hardy sheep or a wind-battered hiker than a legendary greyhound on this exposed northern prow.
