From parking at Llyn Eigiau Reservoir. Tracks to Cedryn, then faint path and fence line to Bwlch y Tri Marchog and summit. A rarely visited summit judging by the lack of wearmarks. Returned via Craig Ffynnon. | PGCE | 26/01/2024 |

Pen Llithrig y Wrach & Clogwyn Llech Lefn with Rufus. Parked in the national park car park behind Joe Brown's in Capel Curig and followed A5 N to ROW leading to south ridge of Pen Llithrig y Wrach. Descending from summit WNW to Bwlch y Tri Marchod and the slight top of Clogwyn Llech Lefn. Followed fence line S from bwlch to pick up original path back to road. Cloud inversion to E & S with lovely views over Tryfan & the high Carneddau. I had PyLW mistakenly logged for 11 years at the time thinking I had done it as part of the southern carneddau circuit, I have finally figured out the logging mistake and ascended this lovely mountain. | jacobrichmond | 21/02/2023 |
