Trip Notes

  • Craig Cwm Silyn, situated in Snowdonia in North Wales, is a mountain that serves as the highest point on the popular Nantlle Ridge route.
  • This mountain features a steep northern face that is favoured by climbers. Towards the west, the Nantlle Ridge stretches over Garnedd Goch and culminates at Mynydd Graig Goch. On the eastern side it dips down before ascending towards Trum y Ddysgl, Mynydd Drws-y-coed and ultimately concludes at Y Garn.
  • It is possible to approach Craig Cwm Silyn from the Beddgelert forest to the east, but for this hike I approached from the west. From this side the ascent profile is a bit gentler.
  • I parked at a small off-road parking area at the end of a long single-track road (OS grid: SH495510). Historically there have been issues with car break-ins at this parking area, and it certainly feels a lot more remote than approaching from the Beddgelert side.
  • The route follows a farm track to the east before picking up a faint path which rises all the way to the summit. To get back to the car, I retraced my steps and went back the same way.
  • At the summit there is a large pile of stones including a small shelter. Whilst I did carry my Yaesu FT-891 HF radio and mast for this activation, the weather conditions were rather poor so only completed a quick activation on the 2-metres band.
  • This is certainly an easier route to the summit, but not as logistically accessible or spectacular as approaching from the eastern side of the ridge.
