Pen yr Ole Wen: A Bold Peak in the Carneddau Range
Pen yr Ole Wen is one of the most striking and formidable peaks in the Carneddau range, standing tall at 978 metres. As the seventh-highest mountain in Wales, it’s a favourite for hikers looking for a challenge, offering rugged ascents, rocky ridges, and some of the most rewarding views in Snowdonia. Known for its dramatic profile overlooking the Ogwen Valley, Pen yr Ole Wen is both a challenge and a triumph for adventurous walkers.
A Steep Climb into the Wild Carneddau
Rising sharply from the shores of Llyn Ogwen, Pen yr Ole Wen is one of the Carneddau’s most iconic peaks. The climb to the summit is steep and demanding, often involving scrambles over loose rock and rough terrain. Once at the top, you’re rewarded with breathtaking views across the Ogwen Valley, the Glyderau mountains, and, on clear days, out towards Anglesey and the Irish Sea.
One of the things that makes Pen yr Ole Wen special is its rugged, no-nonsense character. This is a mountain that feels wild and untamed, where every step up the steep ridges feels like a true achievement. It’s not just about reaching the summit, it’s the journey through rock, scree, and spectacular scenery that makes it memorable.
