According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Gludair", meaning a heap of stones.
Situated near the summit is the Cantilever Stone, a large rock which from the correct angle appears to be precariously balanced, making it a popular place for photographs. Another notable feature, west of the summit, is Castell y Gwynt, (Castle of the Wind), a spiky rocky outcrop.
Bristly Ridge is a grade 1 scramble in Snowdonia. It is located on the north side of Glyder Fach. 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 Sinister Gully and in Great Pinnacle Gap. However these sections may be bypassed in favour of easier lines, reducing the overall difficulty to Grade 1.
