Another adventure with Chris and Nathan. After camping in up by Lynn Idwall, we packed up camp and had an awesome morning scrambling up the north face of Tryfan. All of us jumped A&E. After heading down the south ridge, the weather came in a little, with fog and drizzle, so we abandoned Bristly ridge, and headed east along the Miner's Track (another one!) above Cwm Gwern y Gof the onto the east ridge of the Glyder range. After getting to the top of Glyder Fach, successfully locating the cantilever, we walked along the range to the base Castell Y Gwynt for some lunch in the sun. With a bit of itchy feet, I scrambled around the Castell when waiting for the others. A nice stroll along the top to Glyder Fawr, getting a few pics of the stegosaurus and the Llanberis valley then heading down the scree to the top of Devils Kitchen. Onne last slog up Y Garn, then down it's NE ridge (where some flags where set up for an upcoming ultra), quick v cold dip in Llyn Clyd to complete the loop in the rByronHaywood01/07/2022

Ascent via North Ridge from A5 at SH 6633 6028,to Tryfan, onto Tryfan Far South Peak then up to Glyder Fach via scree at side of Bristly Ridge, on to Castell Y Gwynt. (Well worth the scramble - this peak is deceptive when approaching from this direction and only looks like a small pile of jagged rock but opens out into the most spectacular climb once you're on it - on to Glyder Fawr and descent via Devil's kitchen and Llyn Idwal. A great, tough day, especially in the heat but a lot of great scrambling.lindslow13/06/2021

Climbed solo from Llyn Ogwen via Heather terrace to Bwlch Tryfan, steep path to the east of Bristly ridge, Glyder Fach, Castell y Gwynt, Glyder Fawr, Devil's Kitchen, Llyn Idwal and return to A5. Beautiful calm, sunny and warm day with good views. Time 5 hours. Heather terrace rougher than expected. Final ascent to Glyder Fach very eroded. Completed Welsh 3000'ers with my ascent of Castell y Gwynt, which I had missed out on previous visits. Lovely little scramble up a jagged tor.jamessteel10024/02/2019

Walked as part of a linear walk from Pen y pass to Capel Curig. Bus to Pen y Pass then walked up to Glyder Fawr, Castell y Gwynt, Glyder Fach, Y Foel Goch and Galt Yr Ogof. Terrible mist and wind with no viability of the main Glyders, but the cloud cleared to reveal a beautiful day and spectacular views on Y Foel Goch and Galt Yr Ogof.Lazylizzie04/09/2018
