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.

Lovely views from the top, climb up isn't bad - can be slippery if its wet and in winter.

On the usual northeast to southwest traverse, Garnedd-goch is the final summit of the Nantlle Ridge. Unlike the peaks towards the start of the traverse, Garnedd-goch's rocky summit is found at the end of a much broader section of the ridge. On a clear day, it's a lovely viewpoint for the Lleyn Peninsula and Cardigan Bay beyond.

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.
