Ascended the north ridge of tryfan. Conditions good underfoot with a good build up of snow although a little wet in places. From the summit of tryfan we Descended into Bwlch Tryfan and then ascended the path upto the track junction just before Glyder Fach. Then headed to Y Foel Goch before descending the ridge from Lyn Caseg-Fraith in a NW direction towards Gwern Gof Isaf farm/campsite. Weather a little over cast with only a small amount of breeze.
