We parked at the side of the A5 then across and up past Tal y Llyn Ogwen on the path up roughly following the Afon Lloer but kept looking back across to Tryfan and the Glyders
Once Cwm Lloer is reached the path takes you left up the east ridge of Pen yr Ole Wen
There's some slight scrambling before reaching the summit
A trip southish is a must for views to the Glyders and down Nant Ffrancon
Back up to summit then along the ridge which stays above 3000ft for around 3 miles with the next summit being Carnedd Dafydd
then along the top of the Ysgolion Duon cliffs and eventually up to the highest point of the day Carnedd Llewellyn at1064m
We could see most of northern Snowdonia from Llewellyn such were the clear skies but noticed that the clouds never did leave the top of Snowdon all day even tho its just 20 meters higher. Just down to your luck on the day I suppose. I bet it was rammed on there whereas we only saw about 6 people all day

We descended down a zig zagged path that had a lot of work building retaining stone walls to stop erosion down along the shores of the ressie. Dont know where we went wrong but the path just seemed to stop at the bottom end of the reservoir. we could see the tarmac access road over to our left but could see Tryfan to the right and foolishly thought we knew better than the route we had researched
