The northeastern end of the wonderful Nantlle Ridge is characterised by a sinuous switchback ridge and airy summits. Things start to broaden out a bit once you reach the summit of Craig Cwm Silyn, the high point of the whole ridge at 2,408 feet (734 m). It’s a characterful peak whose craggy northern face, popular with climbers, rises up impressively above the Nantlle Valley.

Hiking

An interesting cairned summit on the way across the Nantlle Ridge. On a sky blue day you couldn't go wrong with the views.

Mountaineering

At 2,408 feet (734 m), Craig Cwm Silyn is the highest point on the Nantlle Ridge. It rewards with glorious views back along the snaking ridgeline, backed by the mighty Snowdon massif. The ascent of its northeast ridge is an entertaining scramble, while Craig Yr Ogof – the mountain's north-facing cliffs – provide plenty of rock climbing interest.

Hiking

The highest peak on the Nantlle Ridge, Craig Cwm Silyn is an excellent viewpoint for northern Snowdonia. The ascent of its rocky, northeast facing spur is an entertaining clamber, while to the west things broaden out towards Garnedd-goch. The mountain's north face, well seen from the village of Nantlle, is steep, rocky and popular with climbers.
