Points of Interest/Notes on this walk:
The South Western ridge of Pen Yr Ole Wen is very, very steep & best tackled in dry, clear conditions. After the intitial rock scramble, the early sections are formed of stone steps. After a short flat area, the gradient steepens &, while it is not severe enough to officially be graded as a scamble, route finding is difficult & you will need to use both hands in lots of places.
Try and find time to have a look underneath Pont Pen-y-benglog (near Ogwen Cottage at the western end of Llyn Ogwen) where the remains of the original stone arched bridge built by Thomas Telford can be seen. Access the river bank is via a stile on NW side of the bridge.
