Did You Know?
- •The name is derived from the Welsh 'Foel', meaning a bare or bald hill, while 'Cocyn' refers to a small mound or heap, neatly describing its profile when viewed from the surrounding valleys.
- •Positioned at the western fringe of the Cadair Idris group, the summit offers an exceptional vantage point for studying the Mawddach Estuary as it snakes toward the sea under the iconic Barmouth Bridge.
- •It is frequently visited as part of a longer circuit including the nearby hills of Pared y Cefn-hir and Craig y Llyn, providing a lower-level, often marshy alternative when the higher summits are lost in the cloud.
- •Despite its status as a Marilyn, its proximity to the more dramatic crags of the main range means you are far more likely to share the summit with a stray sheep than a fellow walker.
