Diffwys: A Southern Sentinel Overlooking the Mawddach
Rising above the Mawddach Estuary on the southern edge of Snowdonia, Diffwys is a quiet, commanding peak in the Rhinogydd range. Standing at 750 metres, this broad-shouldered mountain may lack the craggy drama of its northern neighbours, but it makes up for it with far-reaching views, sweeping ridgelines, and a real sense of remoteness. It’s one of the best places in southern Snowdonia for solitude, sunsets, and wild walking.
Wild Ridges and Big Horizons
Diffwys is a fantastic hill for ridge lovers. Its long summit ridge stretches out to Bwlch Drws Ardudwy, forming a natural boundary above the Ardudwy coastline. From the summit trig point, the panorama is breathtaking, you can see over the Mawddach Estuary, across to Cadair Idris, and even down to the distant Preseli Hills in Pembrokeshire on a clear day. It’s a mountain that rewards those who venture just a little further off the popular routes.
Snowdon’s varied routes mean there’s something for everyone, from leisurely walkers to seasoned hikers. Whether you’re taking the popular Llanberis Path or tackling the exhilarating Crib Goch ridge, each ascent is rewarding in its own way. Reaching the summit is not just about the view; it’s about the journey, the effort, and the stories you’ll tell after.
