Glyder Fach is a mountain in Snowdonia, north-west Wales, and is the second highest of the Glyderau and the sixth highest in Wales. Routes to the summit lead from Tryfan and Bristly Ridge to the north, via Glyder Fawr from Pen-y-Pass to the south, and along the Glyder ridge to the east, towards Capel Curig. It is a popular spot for climbers.

According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Gludair", meaning a heap of stones.

Situated near the summit is Y Gwyliwr, a large rock which from the correct angle appears to be precariously balanced, making it a popular place for photographs. (The name means 'The Sentinel', but is usually anglicised as The Cantilever.[1]) Another notable feature, west of the summit, is Castell y Gwynt, a spiky rocky outcrop.[2]

Bristly Ridge[edit]

Dexter Gully at start of Bristly Ridge

Bristly Ridge (Welsh: Y Grib Bigog[3]) is a scramble in Snowdonia. It is located on the north side of Glyder Fach.[4] Consensus puts the difficulty at Grade 1, but it is at the upper end of the grade and some lines qualify as Grade 2. There are some exposed and steep sections of climbing, particularly the upper pitch of Main Gully (also sometimes known as Dexter Gully) and the direct descent into Great Pinnacle Gap. However these sections may be by-passed in favour of easier lines (e.g., Sinister Gully may be ascended instead of Main Gully; an easier descent into Great Pinnacle Gap can be found on the left (east) side by crossing a sloping slab), reducing the overall difficulty to Grade 1.[5]

Incidental Information[edit]
