Slate Trails and Wild Landscapes
Moel yr Hydd rises from a dramatic landscape shaped by industry and nature. The route to the summit winds through remnants of the area’s slate quarrying past, with old tramways, abandoned workings, and mountain lakes lining the approach. From the top, you’re rewarded with views over Llyn Stwlan, the Moelwyn range, and out toward the distant Rhinogydd.

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.
