Y Garn

Y Garn is a mountain summit reaching 633 meters elevation as part of the Nantlle Ridge within Snowdonia National Park. The peak features a cairn at the top and overlooks surrounding valleys and peaks throughout the park.

The mountain's landscape was shaped by glacial movements during the last ice age roughly 12,000 years ago, creating the valleys and rock formations seen today. These glacial processes established the distinctive ridge profile that defines the Nantlle chain.

This summit is known among hikers who explore the Nantlle region and forms a key waypoint in the local fell-walking tradition of Snowdonia.

The summit can be reached via several routes, with the main path from Rhyd Ddu offering direct access to the peak. Visitors should prepare properly for mountain conditions and bring suitable gear, as weather can change quickly at elevation.

This summit serves as a subsidiary peak to Trum y Ddysgl and is often visited by hikers who want to explore the full Nantlle Ridge. Many walkers include it as a waypoint during longer routes through the mountain range.
