Moelwyn Bach
Moelwyn Bach: The Quiet Twin of Snowdonia’s South
Moelwyn Bach may sit in the shadow of its larger neighbour Moelwyn Mawr, but don’t underestimate this striking summit. Standing at 712 metres, it offers one of the best ridge walks in Snowdonia and some seriously impressive views across the valleys below. With fewer crowds and a rugged, remote feel, Moelwyn Bach is a rewarding climb for those seeking solitude and wild scenery.
A Ridge with a View
Located in the heart of the Moelwynion range, Moelwyn Bach is best known for the spectacular ridge that links it to Moelwyn Mawr. The route is dramatic but manageable, offering a real sense of mountain adventure without technical difficulty. From the summit, you’ll enjoy far-reaching views over Blaenau Ffestiniog, Cwm Croesor, and even as far as the Rhinogydd and Snowdon Massif. The contrast of slate quarries and untouched peaks makes this landscape uniquely Snowdonia.
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.
