November 26, 2023, Craig Cwm Silyn Summit

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.

One of the most aesthetic sections of the Nantlle Ridge, here the terrain narrows to a grassy crest on the approach to Mynydd Tal-y-Mignedd. While relatively narrow, there's no scrambling involved and it's nothing more than a walk, even under winter conditions.

Marking the western end of the awesome Nantlle Ridge Mynydd Craig Goch stands at 610 m and offers amazing views west out to sea.

September 6, 2023, Craig Cwm Silyn Summit

Craig Cwm Silyn at 734 m is the highest point of the Nantlle Ridge. It's a rocky ridge of a summit with good views along the ridge or down into the valleys on each side. Normally run as part of the ridge traverse, it makes a great day out in either direction.

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.
