Glasgwm

Glasgwm is a mountain in the Aran range of southern Snowdonia with steep slopes and rocky faces. The summit stands at 779 meters and is marked by a large cairn of stacked stones.

The mountain long served as a natural boundary between different regions of Gwynedd and was an important landmark for local people. Its distinctive shape makes it easily recognizable from many surrounding valleys.

Local shepherds maintain traditional Welsh farming practices on the mountain slopes, continuing centuries-old methods of hill sheep management.

Hikers can reach the summit from several starting points, with the Cwm Cywarch route offering clearly marked paths. The trails are well-defined on most sections, though rocky areas require careful footing.

Next to the summit lies Llyn y Fign, a mountain lake among the largest found at this altitude beside a peak over 700 meters in England and Wales. This remote lake is often overlooked by visitors, yet it offers a striking contrast to the rocky summit area.
