Craig Cwm Silyn

Craig Cwm Silyn rises to 734 meters and forms the highest point of the Nantlle Ridge in northern Snowdonia. The ridge connects multiple peaks across a series of steep terrain with varied climbing options.

An ancient stone pile on the summit has been reshaped into a wind shelter over centuries of visits. This modification shows how generations of climbers have left their mark on this Welsh peak.

This peak holds significance for hikers pursuing various mountain classification achievements recognized across Britain. These designations bring people from different backgrounds together who share a passion for reaching high points.

The most popular approach is the Nantlle Ridge Traverse starting from Rhyd Ddu and finishing near Llanllyfni, a route that takes several hours. Ordnance Survey map 115 is recommended for navigation since the path crosses steep and exposed sections.

The northern face features sheer vertical cliffs that appeal to experienced rock climbers, while the summit delivers 360-degree views across the entire Welsh landscape. This combination of technical climbing and sweeping vistas makes it popular with different types of mountain enthusiasts.
