The Glyderau (a Welsh plural form, also known in English as the Glyders) are a mountain group in Snowdonia, North Wales. The name derives from the highest peaks in the range, Glyder Fawr and Glyder Fach. According to Sir Ifor Williams, the word "Glyder" derives from the Welsh word "Cludair", meaning a heap of stones.
45. Glyder Fawr via Y Gribin, return via Llyn Idwal. Group: Helen Crowther. Weather: broken cloud, fog on top. Originally planned to scramble up the North face of Glyder Fach, but Helen didn’t feel comfortable so we diverted up Y Gribin.
