Glyder Fach is the 6th highest peak in Wales and the 2nd highest in the Glyderau range. Like its bigger sister (Glyder Fawr), it is an extensive plateau strewn with large bouldrers. Near the large boulders that form its summit, is a famous and seemingly precariously balanced horizontal slab of rock known as The Cantilever (Y Gwyliwr in Welsh, actually meaning The Sentry). Also near the summit on its western side, is a minor top called Castell y Gwynt (Castle of the Wind in English), which is a spectacular formation of upturned spikes of rock with a prominence of 15.7 m, so it does not qualify as a Hewitt. It is also an obstacle that most walkers choose to avoid with a short detour to its south. These two features are better known and much more photographed than is the summit.

See its entries on Walkhighlands or Wikipedia or view it from above on Google Earth.

Glyder derives from the Welsh noun Cluder (commonly spelt Cludair or Clyder with the C soft-mutated to a G following a now lost definite article) meaning a Heap, Stack or Pile (presumably of stones).

Fach is a Welsh adjective (Bach, where the B has been soft-mutated to an F, because it is an adjective qualifying a feminine singular noun) meaning Small, Little or Short.

Therefore, Glyder Fach can be translated as Small Heap of Stones. From the 360° panorama, this name doesn't seem terribly appropriate. Perhaps, Lower or Lesser Heap of Stones might be a better interpretation to make a comparison with Glyder Fawr.
