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.
This was a fantastic day with a Meetup group that I'm a member of. I've wanted to climb Tryfan for ages, and it did not disappoint. We climbed up the north face, and initially I was concerned that we were missing out on some of the best scrambling, so from about 500m altitude, myself and the group organiser took a detour up some steeper rocks. We were both wondering whether we could both actually climb up these rocks initially, and it took us a bit of time to work out the best way up. But it was well worth it - some of the scrambling may have been at the upper end of grade 2!
