is a
Mountain in
Snowdonia in
Wales . It is the most southerly of the
Carneddau range.
The mountain lies to the north of Idwal Cottage
Youth Hostel on the
A5 Road , from where it has a
Pyramid ical appearance. It may climbed from the hostel by a path that leads directly up the south west "corner", climbing 675 m in about 1.5
Km (i.e. an average
Gradient of nearly 1 in 2). A slightly easier ascent involves starting from Tal-y-Llyn Ogwen, about a mile south-east from the hostel, following the stream until nearing the outflow from the mountain lake
Ffynnon Lloer and then branching left to take the path up the ridge.
Pen yr Ole Wen is often climbed as part of a longer route on the Carneddau range.
